Question

*PLEASE HURRY ITS FOR A QUIZ*

In a vacuum, waves from all parts of the electromagnetic spectrum move:

A. with a speed that depends on their energy.

B. with a speed that depends on their frequency.

C. at a speed of light, 300,000,000 m/s.

D. with a speed that depends on their wavelength.

Answer 1

The answer is C! I got it right!

Answer 2

The answer is C. at the Speed of light, 300,000,000 m/s

You need to know that there exists a large family of waves, each with a different wavelength range, called the electromagnetic spectrum (sometimes shortened to the e-m spectrum). These waves all travel at the speed of light (300,000,000 metres per second) in a Vacuum

Good Luck on your test btw
