WebGiven: Velocity of sound in air, v = 336 m/s Velocity of sound in water, v = 1440 m/s Wavelength of sound waves in air, λ = 1.75 m So the frequency of sound in air, f = v λ = 336 1.75 f = 192 Hz [3 marks] Frequency does dont change with the medium, it is the property of the source of sound. WebA transverse sinusoidal wave of amplitude a, wavelength λ and frequency f is travelling on a stretched string. The maximum speed of any point on the string is v / 10, where v is the speed of propagation of the wave. If a =10 3 m and v =10 m / s, then λ is given by A. λ=10 3 mB. λ=π× 10 2 mC. λ=2 π× 10 2 mD. λ=10 2 m

WebProcedure: Take a few zinc granules in a conical flask. Add dilute HCl or H 2 SO 4 into the flask. Observe bubbles of hydrogen gas forming around the zinc granules. If a burning matchstick is brought near the mouth of the flask, then it burns with a pop sound, indicating the evolution of hydrogen gas. Chemical reaction: Zn + 2 HCl → ZnCl 2 + H 2. WebAmplitude – Wave is an energy transport phenomenon. Amplitude is the height of the wave, usually measured in metres. It is directly related to the amount of energy carried by a wave. Wavelength – The distance between identical points in the adjacent cycles of crests of a wave is called a wavelength.

WebA sound is a form of energy that is produced by vibrating bodies. It requires a medium for its propagation. Hence, sound cannot propagate in a vacuum as there will be no material to transfer sound waves. The sound is produced by the back and forth motion of the object. This is known as sound vibration. It is also known as oscillatory motion. WebTone: Tone is defined as the sound which is recognized by its regularity of vibrations. A simple tone will have one frequency while a complex tone will have two or more simple tones known as overtones. Rarefraction: A rarefaction is defined as the region in a longitudinal wave where the particles are apart from each other.

WebSolution: We know that the speed of sound is given by the formula: v = λ ν. Substituting the values in the equation, we get. v = 0.35 m × 2000 Hz = 700 m/s. The time taken by the sound wave to travel a distance of 1.5 km can be calculated as follows: Time = Distance Travelled/ Velocity.
