WebThe explanation for incorrect options: Hertz is the unit of frequency and frequency is defined as the number of vibrations per second. Hence, the number of vibrations per second, which gives frequency in, s e c o n d - 1 = H e r t z. Hence, option (b) is correct. WebSound is defined as vibrations that travel through the air or another medium as an audible mechanical wave. It is produced from a vibrating body. The vibrating body causes the medium (water, air, etc.) around it to vibrate thus producing sound. The sound is produced when something vibrates .

WebSound passes through a tube called an auditory canal. Eardrum (tympanic membrane) → vibrates when the sound incident. Vibrations are sent to the inner ear, from there it goes … 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. leelanau county court cases

WebICSE Selina Class 8 Physics Chapter 7 – Sound explains how vibration or the back and forth movement of an object produce sound. The solutions of the ICSE Selina publication for Class 8 covers all the questions given in the Selina Publication for class 8 in that particular chapter. 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. WebSound is a vibration that travels through the medium in the form of longitudinal waves. This means that sound waves are waves in which the particles of the medium vibrate parallel to the direction of wave propagation. Sound waves are called mechanical waves since they require a medium to propagate. The medium can be solids, liquids or gases. leelanau conservancy hunting
