Question:

What are three properties of electromagnetic waves?
a. they travel slower than the speed of light, they include visible light waves, and they can transfer energy through empty space.
b. they need matter through which to travel, they travel at the speed of light, and they include visible light waves.
c. they travel at the speed of light, they include ultraviolet waves, and they can transfer energy through empty space.
d. they include ultraviolet waves, they need matter through which to travel, and they travel slower than the speed of light.

Answers

The three properties of electromagnetic waves are; they travel at the speed of light, they include ultraviolet waves, and they can transfer energy through empty space.

Further ExplanationA waveA wave is a transmission of a disturbance. It involves transmission of energy from one point which is the source to another point.Waves may be classified depending on the need for a transmission medium or based on the vibration of particles relative to the direction of wave motion.Waves may be either transverse or longitudinal based on the direction of wave motion relative to the vibration of particlesAdditionally waves may be classified as either electromagnetic wave or mechanical based on the need for a transmission medium.Electromagnetic waves  Electromagnetic waves are types of waves that do not require a material medium for transmission.All waves of the electromagnetic spectrum are electromagnetic transverse waves that do not require a material medium for transmission.They include; radio waves, microwaves, infrared, visible light, ultra-violet, x-rays, and gamma rays.All waves of the electromagnetic spectrum travel with a speed of light, 3.0 x10^8 m/s.Additionally, electromagnetic waves possess energy that is given by; E = hf; where h is the plank's constant and f is the frequency.

Answer/Explanation:

They can travel through empty space. (This means if there is no air, it can still travel).

They travel in straight lines. (Think about if you shine a flashlight, it goes straight, not curved. It reflects if it hits something, but then changes direction and continues to travel in straight lines).

They are made of photons. (This is the type of particle the waves are made of).

Option C is the correct answer.
