Electromagnetic Waves - Result Question 30
30. The frequencies of $X$-rays, $\gamma$-rays and ultraviolet rays are respectively $a, b$, and $c$. Then [2000]
(a) $a<b, b<c$
(b) $a<b, b>c$
(c) $a>b, b>c$
(d) $a>b, b<c$
Show Answer
Solution:
- (b) $\gamma$ rays has lowest wavelength and highest frequency among them while ultraviolet ray has highest wavelength and lowest frequency.
Order of frequency : $b>a>c$
