Question

The frequency of $X$ -rays, Gamma rays and visible light wave rays are $a, \, b$ and $c$ respectively, then

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

Answer 1

Answer: (A)

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, $b>a, \, b>c$
