Question

The frequencies of X-rays, Gamma rays and visible light waves 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

The correct option is A $a<b,b>c$

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, $b>a,b>c$
