Question

The speed of electromagnetic waves is vacuum is 3×10^8 meters/sec .
(a) Wave lengths in the visible part of the spectrum (light) range from about 4×10^-7 meter in the violet to about 7×10^-7 In the red . What is the range of frequencies of light wave ?
(b) The range of frequencies for shortwave radio (for example, FM radio and ING wavelength range ? (C) X-rays are also also electromagnetic. Their wavelength range extends from about 5×10^-9 meter to 1.0×10^-11 meter. What is the frequency range for X-rays ?​

Answer 1

Answer:

Generally speaking, we say that light travels in waves, and all electromagnetic radiation travels at the same speed which is about 3.0 * 108 meters per second through a vacuum. We call this the "speed of light"; nothing can move faster than the speed of light.
