Question

What will be the difference between electromagnetic radiation shown in $A$ and $B$ respectively ?

(i) Velocity
(ii) Wavelength
(iii) Frequency
(iv) Energy

• A. (ii) only
• B. (ii) and (iv)
• C. (ii), (iii) and (iv)
• D. (iv) only

Answer 1

Answer: (C)

Electromagnetic waves shown in figure (A) has higher wavelength in comparison to EM waves shown in figure (B).
Thus, these waves also differ in frequency and energy.
$v=\frac{c}{\lambda }$
