Wave velocity is the speed at which a wave propagates through a medium. It depends on the wave type and the properties of the medium. It is given by the formula velocity equals frequency multiplied by wavelength. Different waves like sound water and electromagnetic waves travel at different velocities in various media.
Oscillations in Class 11 Physics cover periodic motion where a system moves back and forth about a mean position. This chapter explains simple harmonic motion, time period, frequency, displacement, velocity, acceleration and energy in oscillations. It also discusses damped and forced oscillations and resonance. Understanding these concepts is important for CBSE Exam 2024 and 2025.
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.
