Progressive Waves

Progressive waves transfer energy.
Transverse waves: Particle oscillation is perpendicular to the wave energy direction
Longitudinal waves: Particle oscillation is parallel to wave energy direction

Wave Characteristics

Amplitude (A): The maximum displacement of a particle from its rest position. The unit is meters (m).
Wavelength (λ): The distance between two adjacent wavefronts. The unit is meters (m).
Frequency (f): The number of complete oscillations of a particle in the wave per unit time. The unit is Hertz (Hz).
Period (T): The time taken for one complete oscillation. The unit is seconds (s).

Wave Speed

Wave speed (v): The distance moved by the wave in a given time.
Formula: v = λ/T = fλ
The unit is meters per second (m/s).

Intensity

Intensity: The rate of energy transmitted (power) per unit area at right angles to the wave velocity.

Stationary Waves

Stationary waves are formed by the superposition of two progressive waves of the same frequency traveling in opposite directions.
They do not transfer energy.
They have fixed points called nodes where the amplitude is zero.
They have points of maximum amplitude called antinodes.

Difference Between Progressive and Stationary Waves

Progressive waves transfer energy.
Stationary waves do not transfer energy.

Energy of a Wave

Waves possess energy.
The amount of energy a wave carries depends on its frequency and amplitude.

This quiz covers the essential concepts of progressive waves, including transverse and longitudinal waves. Students will explore wave characteristics such as amplitude, wavelength, frequency, period, and wave speed, along with intensity and stationary waves. It's designed to test understanding and applications of wave phenomena in physics.
