What is the form of light wave
Answers
Answer:
Explanation:
You are surrounded by electromagnetic waves. They're everywhere! From the light you can see, to the infrared your body is producing, to the ultraviolet coming through your window from the sun. You could not escape the waves if you tried. But then again, why would you want to?
The term light waves can be used differently by different people. Physicists tend to casually use 'light waves' to mean exactly the same thing as electromagnetic waves, but most non-physicists do not. So, what is the difference?
Electromagnetic waves (or electromagnetic radiation) are waves made of oscillating magnetic and electric fields, and include radio waves, microwaves, infrared, visible light, ultraviolet, x-rays and gamma rays. Like all waves, they carry energy, and that energy can be very high-intensity (like the electromagnetic waves we receive from the sun). When looking at the visible light spectrum, the blue end of the electromagnetic spectrum is high frequency, high energy and short wavelength. The red end of the electromagnetic spectrum is low frequency, low energy and long wavelength.
Light is just one part of the electromagnetic spectrum, the part that our eyes can see. So when most people talk about light waves, this is what they mean. However, in physics, 'light waves' often refer to any and all waves in the electromagnetic spectrum, and this is what we will discuss in this lesson.
