SATHEE: Optics Question 311

Optics Question 311

Question: An electromagnetic wave, going through vacuum is described by $E = E_{0} \sin (k x - ω t)$ . Which of the following is independent of wavelength

Options:

A) k

B) w

C) k/w

D) kw

Show Answer

Answer:

Correct Answer: C

Solution:

The angular wave number $k = \frac{2 π}{λ};$ where l is the wave length. The angular frequency is $w = 2 π ν .$ The ratio $\frac{k}{ω} = \frac{2 π / λ}{2 π ν} = \frac{1}{ν π} = \frac{1}{c}$ = constant
