The frequencies of $X-$ rays, Gamma rays and visible light waves rays are $a, b$ and $c$ respectively, then
Updated On: May 12, 2022
- $a > b > c$
- $a > b, b < c$
- $a < b, b > c$
- $a < b, b < c$
Hide Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
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, $b > a, b >c$
$a=3 \times 10^{19}$ 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, $b > a, b >c$

Electromagnetic Spectrum
The term used by scientists to describe the entire range of light that exists is the electrostatic spectrum. Light is a wave of alternating electric and magnetic fields. The propagation of light doesn't vary from waves crossing an ocean. Like any other wave, light also has a few fundamental properties that describe it. One is its frequency. The frequency is measured in Hz, which counts the number of waves that pass by a point in one second.
The electromagnetic waves that your eyes detect are visible light and oscillate between 400 and 790 terahertz (THz). That’s several hundred trillion times a second.
