Solution

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
Assertion:
Electromagnetic waves have different energies which are dependent on the wavelengths or frequencies of the waves. Therefore, the frequencies and wavelength are the parameters that differentiate between the different Electromagnetic waves.

Reason:
The speed is for all the electromagnetic waves is the same in the vacuum. Al the waves travel at the speed of light $i . e . 3 \times 10^{8} m / s$ .

Thus, Both Assertion and Reason are correct and Reason is the correct explanation of Assertion.
