Q. What is true for ALL of the examples of electromagnetic waves? They all move at the same speed in a vacuum.An electromagnetic wave can travel through anything – be it air, a solid material or vacuum. It does not need a medium to propagate or travel from one place to another. Mechanical waves (like sound waves or water waves), on the other hand, need a medium to travel. EM waves are ‘transverse’ waves.All electromagnetic waves: are transverse waves; can travel through a vacuum ; travel at exactly the same speed in a vacuum, the speed of light, 300,000,000 m/s.

Do all electromagnetic waves have the same wavelength?
When you listen to the radio, watch TV, or cook dinner in a microwave oven, you are using electromagnetic waves. Radio waves, television waves, and microwaves are all types of electromagnetic waves. They only differ from each other in wavelength.
Do all electromagnetic waves have the same energy?
In that section, it was pointed out that the only difference between radio waves, visible light and gamma rays is the energy of the photons. Radio waves have photons with the lowest energies. Microwaves have a little more energy than radio waves.
Do electromagnetic waves carry energy and momentum?
Yes, the electromagnetic waves carry both energy and momentum.
Do all electromagnetic waves travel at the same speed?
Electromagnetic radiation is a type of energy that is commonly known as light. Generally, light travels in waves, and all electromagnetic radiation travels at the same speed, which is about 3.0 × 108 ms− 1 through a vacuum.

Are electromagnetic waves longitudinal?
The most common transverse and longitudinal waves are light waves and sound waves, respectively. All electromagnetic waves (light waves, microwaves, X-rays, radio waves) are transverse. All sound waves are longitudinal.
Which is false about electromagnetic waves?
Explanation: Electromagnetic waves are the combination of mutually perpendicular electric and magnetic fields. So, option (c) is false.
Which of the following statement is not true about EM waves?
Expert-verified answer
D) EM waves form when energy is transferred through the field is incorrect about electromagnetic waves. Electromagnetic waves are formed when an electric field and magnetic field come in contact with each other.
What are the important characteristics of electromagnetic waves?
- Characteristic of electromagnetic waves are as follows: –
- (i) They do not require any material medium for their propagation.
- (ii) The oscillations of and are perpendicular to each other and are in same phase.
- (iii) They are transverse in nature.
- (iv) They travel through vacuum with same speed,
Which statement is true about a mechanical wave but not true about electromagnetic radiation?
Answer: The speed of an electromagnetic wave can be affected by a medium, but the speed of a mechanical wave cannot.
Which electromagnetic wave has the longest wavelength?
Radio Waves — The waves in the electromagnetic spectrum that have the longest wavelengths and lowest frequency are called radio waves.
Which of the electromagnetic waves have the least wavelength?
Gamma ray has the shortest wavelength and ultraviolet has the third shortest wavelength in EM spectrum. Was this answer helpful?

What two things do electromagnetic waves have?
ELECTROMAGNETIC WAVES
A changing magnetic field will induce a changing electric field and vice-versa—the two are linked. These changing fields form electromagnetic waves. Electromagnetic waves differ from mechanical waves in that they do not require a medium to propagate.
Can all EM waves be reflected and refracted?
Because electromagnetic radiations are waves, they exhibit all of the properties we have discussed for mechanical waves. Thus, light waves and radio waves can be reflected and refracted, and they exhibit diffraction and interference.
