Speed of sound depends on the density and elasticity of the medium. It can be defined using the formula: v = √(B/ρ) Where, - B is the bulk modulus, which is nothing but elasticity of the medium. - ρ is the density of the medium.

Speed of sound depends on the density and elasticity of the medium. It can be defined using the formula:
v = √(B/ρ)
Where,
– B is the bulk modulus, which is nothing but elasticity of the medium.
– ρ is the density of the medium.
Since the bulk modulus in solids is way more than that of gases and liquids, sound will travel fastest in a solid. Out of the above options, steel has the highest elasticity: so, the speed of sound is maximum in steel.
The right answer is T = 1/f. The time period (T) of a wave is defined as the amount of time it takes for one complete cycle of the wave. It is related to frequency (f) by the formula: T = 1/f where: - T is time period (in seconds), - f is frequency (in hertz, Hz). This is the inverse relation; it isRead more
The right answer is T = 1/f.
The time period (T) of a wave is defined as the amount of time it takes for one complete cycle of the wave. It is related to frequency (f) by the formula:
T = 1/f
where:
– T is time period (in seconds),
– f is frequency (in hertz, Hz).
This is the inverse relation; it is such that as the frequency is higher, the time period will be less, and vice versa.
In a longitudinal wave, the particles of the medium oscillate parallel to the direction of wave propagation. This creates regions of compressions (high pressure) and rarefactions (low pressure). Examples of longitudinal waves include sound waves in air, where air molecules move back and forth alongRead more

The wave velocity (v), the wavelength (λ), and frequency (f) are related by the equation: v = fλ where: - v, the wave velocity, is measured in meters per second (m/s), - f , the frequency, is measured in hertz (Hz) - λ, the wavelength, is measured in meters (m).

The wave velocity (v), the wavelength (λ), and frequency (f) are related by the equation:
v = fλ
where:
– v, the wave velocity, is measured in meters per second (m/s),
– f , the frequency, is measured in hertz (Hz)
– λ, the wavelength, is measured in meters (m).
This equation proves that the speed of a wave is the product of its frequency and wavelength.
A mechanical wave needs a medium (air, water, or solids) in which to propagate. Since it travels along compressions and rarefactions in a medium, sound waves are mechanical waves. Light waves, radio waves, and X-rays are electromagnetic waves, unrelated to a medium and certainly able to travel throuRead more
