Description : The quality of sound depends upon its (a) Waveform (b) Frequency (c) Loudness (d) Pitch
Last Answer : Ans:(a)
Description : The pitch of sound is measured by its (a) Intensity (b) Waveform (c) Frequency (d) Loudness
Description : Loudness of sound depends on – (1) Frequency (2) Wavelength (3) Amplitude (4) Pitch
Last Answer : (3) Amplitude Explanation: Loudness depends on the amplitude of the sound wave. The larger the amplitude the more energy the sound wave contains therefore the louder the sound. The pitch of a note depends on the frequency of the source of the sound.
Description : Which among the following determines the pitch of a sound? (1) Amplitude (2) Frequency (3) Loudness (4) Wavelength
Last Answer : (2) Frequency Explanation: The pitch of a sound is determined by the frequency of vibration of the sound waves So higher the frequency the higher is the pitch.
Description : The pitch of the sound is measured by its: (1) Intensity (2) waveform (3) Frequency (4) Loudness
Last Answer : (3) Frequency Explanation: Pitch relates to the frequency, or how many times a second the particles vibrate. The distance between one wave and the next gives the wavelength. For sounds all travelling at the same speed, highfrequency (high-pitched) sounds have waves very close together.
Description : The pitch of sound depends on its – (1) Frequency (2) Intensity (3) Velocity (4) Amplitude
Last Answer : (1) Frequency Explanation: Pitch is a perceptual property that allows the ordering of sounds on a frequencyrelated scale. Pitch may be quantified as a frequency, but pitch is not a purely objective physical property; it is a subjective psychoacoustical attribute of sound.

Description : The swing of a spinning cricket ball in air can be explained on the basis of (a) Sudden change in wind direction (b) Buoyancy of air (c) Turbulence caused by wind (d) Bernoulli’s theorem
Last Answer : Ans:(d)
Description : The swing of a spinning cricket ball in air can be explained on the basis of – (1) Sudden change in wind direction. (2) Buoyancy of air. (3) Turbulence caused by wind. (4) Bernoulli's theorem.
Last Answer : (3) Turbulence caused by wind. Explanation: The main theory of swing bowling surrounded turbulent and laminar airflow. Laminar air separates from the surface of the ball earlier than turbulent flow air, ... towards the back; inducing a greater lift force on the turbulent airflow side of the ball.
