The frequency of a given region of the electromagnetic spectrum ranges from 3 × 1016 − 3 × 1019 hertz. Which type of wave is found in this region?

Ax-rays
Bultraviolet rays
Cinfrared waves
Dradio waves

Verified Answer :

Wavelength = (speed) / (frequency)
Speed of EM radiation = 3 x 10⁸ m/s

Frequency (3 × 10¹⁹ Hz)  ===>  wavelength  =  0.01 nanometer

Frequency (3 × 10¹⁶ Hz)  ===>  wavelength  =  10 nanometers

This is the region of X-rays.

The correct answer to the question is : A) X -rays.

EXPLANATION:

As per the question, the frequency of the given radiation is \(3\times 10^{16} -\ 3\times 10^{19}\ Hz.\).

If we arrange all the electromagnetic radiations in the ascending order of their frequency, then the given frequency is less than the frequency of gamma wave and greater than U.V ray.

The given frequency corresponds to the frequency of X-rays in the electromagnetic spectrum.

Hence, the correct answer of the question is X-rays.
