The subjective property of light and sound which depends on the wavelength are:
Frequency
Colour, pitch
Speed, Frequency
Intensity
Colour, Pitch
Each of the properties of sound listed in column A primarily depends on one of the quantities in column B. Choose the matching pairs from two columns
Column A Column B
Pitch Waveform
Quality Frequency
Loudness Intensity
Write true or false for each statement:
(a) When sound propagates in air,it does not carry energy with it.
(b) In a longitudinal wave,compression and rarefaction are formed.
(c) The distance from one compression to nearest rarefaction is called wavelength.
(d) The frequency is measured in second.
(e) The quality of sound depends on the amplitude of wave..
(f) The pitch of sound depends on frequency..
(g) Decibel is the unit of pitch of a sound.
