Answer:
A and B
Explanation:
The relation between frequency and wavelength is shown below as:
c is the speed of light having value
Thus, the product of the wavelength and the frequency is constant and equal to
<u>Option A is correct.</u>
Given, Frequency =
Thus, Wavelength is:
Also, 1 m = Å
So,
<u>Wavelength = 3.0 Å</u>
<u>Option B is correct.</u>
As stated above, the speed of electromagnetic radiation is constant. Hence, each radiation of the spectrum travels with same speed.
<u>Option C is incorrect.</u>
