(a) Following are the ways in which sound can be produced: (i) by vibrating the strings (ii) by vibrating membranes (iii) by vibrating the pl...
Sound waves in air: longitudinal, compression, rarefaction Water waves: transverse, crest, trough
The flash of gun shot reaches first because the light waves travel faster than the sound waves of the gun shot.
The flash of lightning reaches us first and then the sound of thunder because light waves travel faster than the sound waves.
We see the bat hitting the ball first and then hear the sound because light travels faster than the sound.
(a) In longitudinal waves, the particles move back and forth in the same direction whereas in transverse waves, the particles move up and down. Lon...
Amplitude is defined as the maximum displacement of the particle from its original undisturbed position. figure.png
Vacuum is defined as the empty space in which there are no matter particles present. Sound cannot travel through vacuum as there is no particles prese...
(a) Vibrations (b) Compression, lower, and rarefaction (c) Hertz, wavelength, and meters (d) Vacuum (e) Greater (f) Decreases
The frequency in hertz is 20 hertz as the hertz is the representation of number of waves produced per second.
Velocity of sound is the product of frequency and wavelength. The speed of sound in air is constant. Therefore, when the frequency is doubled, wavelen...
Frequency = = = 50 Hz
We know that, Frequency = 200 Hz Frequency = Time period = = 5 × 10-9 s
The number 256 on the tuning fork signifies the frequency of the tuning fork.
Sound travels faster in hydrogen.
Supersonic is the terms that is used for denoting the speed which is greater than the speed of sound.
Slowest is the sound Fastest is the light
False, Sound produced by a vibrating body travels to our ears by the actual movement of air.
The conclusion that can be obtained from the observation when the prongs of tuning fork touches the surface of water is that the vibrations from the t...
The nature of sound waves in air is longitudinal waves.
