1)An electromagnetic wave has a wavelength of 6.2 x 10^14 n. What is the frequency of the wave?
3.00 x 10^8 * 6.2 x 10^14
1.8 x 10^24 = frequency
2)The velocity of an electromagnetic wave depends on:
its wavelength and frequency
Both are wrong. In one, I wonder where you got the first formula.
2) What determines the veloicity oflight in glass? You need to think about the medium.
To find the frequency of an electromagnetic wave, you need to use the equation:
frequency = speed of light / wavelength
The speed of light in a vacuum is approximately 3.00 x 10^8 meters per second. In this case, the wavelength is given as 6.2 x 10^14 meters.
So, to find the frequency, you divide the speed of light by the wavelength:
frequency = 3.00 x 10^8 / (6.2 x 10^14)
This simplifies to:
frequency = 4.84 x 10^-7
Therefore, the frequency of the wave is approximately 4.84 x 10^-7 Hz.
As for the second question, the velocity of an electromagnetic wave in a vacuum is constant and is equal to the speed of light. It does not depend on either wavelength or frequency. The speed of light is approximately 3.00 x 10^8 meters per second.
