Question 152: EM waves

Question

Arrange the following electromagnetic
radiations per quantum in the order of
increasing energy :
A : Blue light           B : Yellow light
C : X-ray                 D : Radiowave.

Accepted Answer

Energy is in terms of increasing wavelength, we have
$$\lambda$$
X-rays
< $$\lambda$$
Blue light
< $$\lambda$$
Yellow light
< $$\lambda$$
Radio waves
Since $$E = {{hc} \over \lambda }$$
Therefore, order of increasing energy is
E
Radio waves
< E
Yellow light
< E
Blue light
< E
X-rays
