Question

The speed of a wave is determined by multiplying the _________ of the wave by its wavelength. In a vacuum all electromagnetic radiation travels at a constant speed, the speed of _________________ , which is equal to 3.00 x 108 m/s. (Include a word in the last fill in the blank space, not a number.)

Answer 1

The speed of a wave is found by multiplying the frequency by its wavelength, and in a vacuum, all forms of electromagnetic waves travel at the speed of light, which is 3.00 x 10^8 m/s.

Step-by-step explanation:

The speed of a wave is determined by multiplying the frequency of the wave by its wavelength. In a vacuum, all electromagnetic radiation travels at a constant speed, the speed of light, which is equal to 3.00 x 108 m/s.

Electromagnetic radiation consists of two perpendicular waves, one electric and one magnetic, both propagating at the speed of light. Regardless of their different frequencies and wavelengths, all forms of electromagnetic radiation, such as radio waves, microwaves, visible light, x-rays, and gamma rays, travel through a vacuum at this unvarying speed.
