Question

The diagram shows a wave. The quantity shown is the amplitude. This quantity is directly proportional to which of these other quantities? A) Energy B) Frequency C) Period D) Wavelength

Answer 1

Answer:

A. Energy

Explanation:

Answer 2

As we know that frequency and wavelength are dependent on each other

and this is given by

$f = \frac{c}{\lambda}$

here we know that

$\lambda$ = wavelength

f = frequency

c = speed of wave

while for energy and intensity of wave we know that

Energy = $KA^2$

here A = amplitude of wave

so energy directly depends on amplitude of wave

so correct answer will be

A) Energy
