Vibrations and Waves in Physics Quiz

Sound waves require a medium such as air, water, or solid to propagate.

Hertz is the unit of frequency, representing one cycle per second.

In transverse waves, particles of the medium vibrate perpendicular to the direction of wave propagation.

Frequency and wavelength of a wave are inversely proportional to each other.

Diffraction is the bending of waves around obstacles or through openings.

Sound travels fastest through steel due to its high elasticity.

Factors like density, elasticity, and temperature of the medium collectively determine the speed of sound.

The Doppler effect causes a change in frequency due to relative motion between the source and the observer.

In the equation, 'T' represents the tension in the medium through which the wave travels.

Interference is the phenomenon where two waves combine to form a resultant wave.

Phase refers to the position of a point in a wave cycle, often measured in degrees.

The period of a pendulum is affected by its length.

The equation v = λf represents the relationship between velocity (v), wavelength (λ), and frequency (f) of a wave.

Light waves are electromagnetic waves, not mechanical waves.

Refraction is the phenomenon where a wave changes direction upon crossing a boundary between media of different densities.

Refraction explains why waves bend as they pass from one medium to another with a different density.

Resonance occurs when a system is driven at its natural frequency, resulting in an increase in amplitude of vibrations.
