Question

Which wave characteristic/s is/are increasing from left to right of the spectrum?

a) speed
b) wavelength
c) frequency
d) amplitude​

Answer 1

Frequency of the wave are increasing from left to right.

But why?

• First of all, look at the waves on the left side of the electromagnetic spectrum. You will notice that the wavelength is longer and the frequency is lesser. Hence, the energy of the waves (i.e. radio waves, microwaves and infrared ray have smaller energy) is less.

$\boxed{ \bf \: E \propto \: \nu} \: \: \: \: \: . \: . \: . \rm(\nu \: is \: freq.)$

• Now, look at the waves on the right side of the electromagnetic spectrum. The waves have lesser wavelength and more frequency.

• So on the right side, the waves (X ray, Gamma ray) have higher energy.

Hence, frequency is increasing from left to right.

• And, since the maximum displacement of the wave is remaining constant whole throughout, we can say that the amplitude is also remaining constant.
