The grating intensity expression gives a peak intensity which is proportional to the square of the number of slits illuminated. Increasing the number of slits not only makes the diffraction maximum sharper, but also much more intense.As the number of slits is increased, the intensity of the principal maxima increases and the width decreases.Diffraction gratings are often identified by the number of lines per centimeter; gratings with more lines per centimeter are usually more useful because the greater the number of lines, the smaller the distance between the lines, and the greater the separation of images on the screen.
What is the effect of increasing the number of slits on the intensity of central maxima of diffraction pattern?
As the number of slits is increased, the intensity of the principal maxima increases and the width decreases.
What is the effect of increasing the number lines per cm of the grating on the diffraction pattern?
Diffraction gratings are often identified by the number of lines per centimeter; gratings with more lines per centimeter are usually more useful because the greater the number of lines, the smaller the distance between the lines, and the greater the separation of images on the screen.

How does increasing number of slits affect the interference pattern?
Increasing the number of slits increases the number of angles at which destructive (or almost destructive) interference can occur, while the condition for constructive interference remains just the same (nλ=d sinθ for a transmission grating at normal incidence).
How does the number of lines slits in a diffraction grating affect the width of interference maxima?
As the number of slits is increased, the width of the maxima decreases (and they get brighter).
What happens when you decrease the number of slits in a diffraction grating?
Maxima can be produced at the same angles, but those for the diffraction grating are narrower and hence sharper. The maxima become narrower and the regions between darker as the number of slits is increased.
How does the single slit pattern change as you increase the slit size?
It gets narrower. This is true for single slits, double slits, and diffraction gratings. The smaller the object the wave interacts with, the more spread there is in the interference pattern. Increasing the size of the opening reduces the spread in the pattern.
What effect will increasing the number of lines per mm have on the grating constant of a diffraction grating?
i) with the increase in number of lines the secondary maxima relative to the principal maxima decreases and becomes negligible. The principal maxima become more sharp and intense.

What will happen if no of lines per cm is increased?
What happens to the diffraction pattern when the number of lines per centimeter of a diffraction grating is increased? A. Nothing happens to the diffraction pattern.
What is the advantages of increasing the number of lines in a grating?
Advantages of increasing the number of lines in the grating are: a The number of principle maxima that can be seen on a screen increase. b The distance between two adjacent principle maxima increases.
How does the number of slits affect the intensity in diffraction?
The grating intensity expression gives a peak intensity which is proportional to the square of the number of slits illuminated. Increasing the number of slits not only makes the diffraction maximum sharper, but also much more intense.
How does the width of the slits affect the intensity in diffraction?
When the widths of the slits are greater than the wavelength of the light, the light casts the shadow. When the widths of the slits are narrow, light undergoes diffraction and the light waves overlap on the screen. Hence, the intensity of the light is more as the width of the slit increases.

Why does increasing the number of slits in a diffraction grating improve the resolution capabilities of that grating?
By using more slits, you get more destructive interference. The maxima on the other hand become much brighter because of increased constructive interference. This effectively increases the resolution of the experiment, making it easier to measure the distance between consecutive maxima.
How do you determine the number of slits in a diffraction grating?
The number of slits per metre on the grating, N = 1/ d where d is the grating spacing. For a given order and wavelength, the smaller the value of d, the greater the angle of diffraction. In other words, the larger the number of slits per metre, the bigger the angle of diffraction.
What happens to the angular separation between the lines with an increase in the order?
Angular separation would remain same when the distance of separation between the slit and the screen is doubled.
What happens when the size of the grating element is increased?
∴ resolving power ∝ number of grating lines
Hence, if the number of lines of a grating is increased, its resolving power will also increase.
What will be the effect on fringe width when distance between slits become doubled?
EXPLANATION: The fringe width is inversely proportional to the distance between the slits. When the distance between the slit is doubled the fringe width becomes half.
What is the effect of increasing the slit separation?
As the slit separation increased, the fringe width decreased, meaning there was less interference. Also, as the distance between the slits and the wall increased, the fringe width increased, because the light would have more space to diffract outwards, and thus be able to interfere more.
What happens when the slit width decreases?
If we increase the width size, a, the angle T at which the intensity first becomes zero decreases, resulting in a narrower central band. And if we make the slit width smaller, the angle T increases, giving a wider central band.
How do you increase diffraction?
The amount of diffraction (the sharpness of the bending) increases with increasing wavelength and decreases with decreasing wavelength. In fact, when the wavelength of the waves is smaller than the obstacle, no noticeable diffraction occurs.
How the grating element is related with no of lines drawn per unit length of the grating?
d = \frac {1} { N }, where N is the grating constant, and it is the number of lines per unit length. Also, n is the order of grating, which is a positive integer, representing the repetition of the spectrum.

What is the distance between slits in diffraction grating?
Image 3 As light travels through the slit, it transmits through the diffraction grating at different angles θ. The distance between the grooves is ‘d’. If there are 1000 grooves per millimeter, and we want to know the distance between the grooves, we divide the length (1 mm) by the number of grooves (1000).
Will the angular separation between orders of Maxima increase or decrease with more lines per mm on the grating?
Grating equation
d = separation of slits θ = angle from zero order to nth maximum. λ and d must be in metres. , then it can be seen that to increase θ, the separation of the maxima, you can: increase the wavelength, i.e. move from blue towards red light decrease the slit separation, i.e. have more lines per mm.
