Question

(i) Which wave produces shrill sound, Wave A or Wave B ?

(ii) Which wave shows lower frequency, Wave A or Wave B?

(iii) Which wave shows lower amplitude, Wave C or Wave D?

(iv) Which wave shows higher loudness of sound, Wave C or Wave D?

(v) What is the frequency of Wave C?​

Answer 1

Answer:

(i) Wave B produces shrill sound because the wavelength is shorter in Wave B.

(ii) Wave A shows lower frequency because the distance or wavelength of waver is more in wave A . That's why frequency is lesser in Wave A.

(iii) Wave C shows lower amplitude beacause the displacement is less in the wave C.

(iv) Wave D shows higher loudness of sound beacause amplitude is higher in wave D.

(v) frequency = no. of waves/ time

f = 2 / 1

f = 2 Hz.
