CBSEENPH12038148

The velocity of propagation (in vacuum) and the frequency of (i) X-rays and (ii) radio waves are denoted by (v1, n1) and (v2, n2) respectively. How do the value of (a) v1 and v2(b) n1 and n2 compare with each other?

Solution

Velocity and frequency of X-rays = (v1 , n1
Velocity and frequency of radio waves = (v2 , n2 )

(a)  v1v2>1  or  v1 = v2  

(b) n1n2>1  or  n1>n2. 

The above expression compares the values of v1, v2, n1 and n2
