Question
Ch 24: electromagnetic waves
4. How is the energy of the electromagnetic wave divided between the parts of the wave?
8. What are the range of frequencies and wavelengths of the visible part of the spectrum?
10.What is the relationship between the ray showing the direction of motion the wave moves and the wave front of the wave?
13. If a second polarizer has its transmission axis perpendicular to the first polarizer, what is the intensity of the light that exits the second polarizer?
14. If a third polarizer is placed between the first two but its transmission axis is not lined up with either transmission axis, will the intensity of the light that exits the last polarizer be the same as the previous question? Why or why not?
Please answer these question thank you they are all concerning this chapter thanks !!
Explanation / Answer
4.
Energy is divided based on the wavelength or frequency of each wave.
8.
wavelength: 400 nm to 700 nm
frequency : 430 to 790 THz
10.
Both will be perpendicular to each other at any point of time.
13.
Zero
14.
Not zero.
As the middle one is not aligned perpendicular to third one some light will pass through third one.
