Question

The frequencies of $X-$ rays, Gamma rays and visible light waves rays are $a, b$ and $c$ respectively, then

• A. $a > b > c$
• B. $a > b, b < c$
• C. $a < b, b > c$
• D. $a < b, b < c$

Answer 1

Answer: (C)

$a < b, b > c$

Answer 2

The frequency of $X$ -rays
$a=3 \times 10^{19}$ to $1 \times 10^{16}$
The frequency of Gamma-rays
$b=3 \times 10^{22}$ to $3 \times 10^{18}$
The frequency of visible light
$c=8 \times 10^{14}$ to $4 \times 10^{14}$
So, $b > a, b >c$
