Q7 / 30 · NTA Abhyas (NEET) 2020 · Physics · Electromagnetic Waves

The frequencies of $X$ -rays, $γ$ -rays and ultraviolet rays are respectively $a$ , $b$ and $c$ . Then

A
$a < b, b < c$
Correct answer
B
$a < b, b > c$
C
$a > b, b > c$
D
$a > b, b < c$

Solution

γ

rays has lowest wavelength and highest frequency among them while ultraviolet ray has highest wavelength and lowest frequency.

Hence, the correct answer is option: 'B'.
