Question

which of the following statements is true regarding electromagnetic radiation?

Options:

1. electromagnetic radiation with a wavelength of 600 nm travels faster than that with a wavelength of 400 nm.

2. the frequency of electromagnetic radiation determines how fast it travels.

3. Electromagnetic radiation with a wavelength of 400 nm travels faster than that with a wavelength of 600 nm.

4. electromagnetic radiation with a wavelength of 600 nm has a frequency that is lower than that with a wavelength of 400 nm.

5. electromagnetic radiation with a wavelength of 400 nm has a frequency that is lower than that with a wavelength of 600 nm.

Answer 1

c = frequency x wavelength = 3 x 10^8 m/s = constant.
That one equation should give you the answers you need.

Answer 2
