Question 17

[Maximum number: 1]

In the diagram, the mountaineer can hear the stream although he cannot see it. When he is closer to the gully, he can both hear and see the stream. When he is further from the gully, he can neither hear nor see the stream.

Question image

Which statement is not correct?

A

As he approaches the gully edge, he hears first the short wavelength, higher frequencies and then the long wavelength, lower frequencies.

B

As he approaches the gully edge, the sound becomes louder.

C

He hears the stream because some of the sound is diffracted.

D

He hears the stream because some of the sound is reflected from the opposite wall of the gully.

Question 17

[Maximum number: 1]

Light diffracts when it enters a telescope. This causes the image to blur slightly. The amount of diffraction depends on the diameter of the hole through which the light enters the telescope and the wavelength of the light.

Which combination for diameter and wavelength will result in the sharpest image (least blurring)?
