How does the wave pattern of a loud note differ from a soft note ? Draw a diagram
What is longitudinal wave ?
Write true or false
In a longitudinal wave, compression and rarefaction are formed.
Two waves have frequencies 256 Hz and 512 Hz, but same amplitude. Compare their (i) loudness, and (ii) pitch
Define the following terms :(a) Amplitude(b) Frequency(c) Time period.
If the amplitude of a wave is doubled, what will be the effect on its loudness ?
State three factors on which loudness of sound heard by a listener depends.
Select the correct alternative
The safe limit of loudness of audible sound is
