(A) whistle of train (B) roar of a lion
Three sounds 5 Hz, 500 Hz and 50,00 Hz are procued by different sources.
Which sounds may be produced by bats?

Consider two cases (A) whistle of train (B) roar of a lion Three sounds 5 Hz, 500 Hz and 50,00 Hz are procued by different sources. Which sounds may be produced by elephants?

Consider two cases (A) whistle of train (B) roar of a lion Three sounds 5 Hz, 500 Hz and 50,00 Hz are procued by different sources. Which sound will be heard by humans?

Consider two cases (A) whistle of train (B) roar of a lion In which case the sound is high pitch?

Consider two cases (A) whistle of train (B) roar of a lion What is the real cause of sound production? Explain with examples.

The tuning forks of frequencies 320 Hz and 340 Hz produce sound waves of wavelength differing by 6 cm in air. The velocity of sound in air is

A car is moving with a speed of 72 km-hour^(-1) towards a roadside source that enits sound at a frequency of 850 Hz. The car driver listens to the sound while approching the source and again while moving away from the source after crossing it. If the velocity of sound is 340 ms^(-1) , the difference of the two frequencies the driver hears is

A source of sound S is moving with a velocity 50 m//s towards a stationary observer. The observer measures the frequency of the source as 1000 Hz. What will be the apparent frequency of the source when it is moving away from the observer after crossing him? The velocity of sound in the medium is 350 m//s .

Calculate the velocity of sound in gas in which two waves of wavelengths 50 cm and 50.5 cm produce 6 beats per second.

A tuning fork is used to produce resonance in glass tuve. The length of the air column in the tube can be adjusted by a variable piston. At room temperature of 27^@C two succesive resonance are produced at 20 cm and 73 cm column length. If the frequency of the tuning fork is 320 Hz. the velocity of sound is air at 27^(@)C is

Two trains A and B moving with speeds 20m//s and 30m//s respectively in the same direction on the same straight track, with B ahead of A . The engines are at the front ends. The engine of train A blows a long whistle. Assume that the sound of the whistle is composed of components varying in frequency from f_(1) = 800 Hz to f_(2) = 1120 Hz , as shown in the figure. The spread in the frequency (highest frequency - lowest frequency) is thus 320 Hz . The speed of sound in still air is 340 m//s .The speed of sound of the whistle is
