Q. What is speed of light wave?
Ans.
Light is just one type of wave. Like all waves it can be characterized by frequency, wavelength and amplitude. Similarly, light waves carry energy. Solar panels and solar ovens take advantage of the energy transferred by light. Energy in this form is also known as electromagnetic radiation.
The speed of light in a vacuum is a known quantity and, so far, no one has discovered anything that can go faster than light in a vacuum. It is the universal speed limit. The speed of light, usually written as the letter c for short, has an approximate value of 3.00 x 108m/s.
c = 3.00 x 108 m/s
The wavelength and frequency of the light are related to the speed in the following way:
c = λv
