Description : The sound heard after reflection from a rigid surface is called an
Last Answer : echo.
Description : What is the difference of absorption and reflection of sound?
Last Answer : What is the answer ?
Description : A man is sitting by the side of a large lake. He hears the utterances of bathers with their mouth close to water surface more clearly than if they were at same distance away on land. This ... due to sound waves undergoing (a) Reflection (b) Refraction (c) Dispersion (d) Total internal reflection
Last Answer : Ans:(c)
Description : Which phenomenon is responsible for the echo of sound wave? (1) Reflection (2) Refraction (3) Interference (4) Polarization
Last Answer : (1) Reflection Explanation: Reflection of sound waves off of surfaces lead to one of two phenomena - an echo or a reverberation. The echo is produced due to hitting of the sound waves with the ... reflected sound wave reaches the ear more than 0.1 seconds after the original sound wave was heard.
Description : Sound and light waves both _______. (1) have similar wavelength (2) obey the laws of reflection (3) travel as longitudinal waves (4) travel through vacuum
Last Answer : (2) obey the laws of reflection Explanation: The two laws of reflection of light are applicable to sound waves as well. The incident wave, the normal to the reflecting surface and the reflected wave at the point of incidence lie in the same plane.
Description : When a vibrating tuning fork is placed on a table, a loud sound is heard. This is due to – (1) reflection (2) refraction (3) forced vibrations (4) damped vibrations
Last Answer : (3) forced vibrations Explanation: The tendency of one object to force another adjoining or interconnected object into vibrational motion is referred to as a forced vibration. In the case of the ... forced into vibration. This causes an increase in the amplitude and thus loudness of the sound.
