Study Notes

Mechanical Waves: require a physical medium to propagate, e.g., water waves, sound waves
Electromagnetic Waves: do not require a physical medium, e.g., light, radio waves, X-rays

Amplitude: maximum displacement of a wave from its equilibrium position
Wavelength: distance between two consecutive points on a wave that are in phase
Frequency: number of oscillations or cycles per second, measured in Hz
Speed: distance traveled by a wave per unit time, measured in m/s
Period: time taken by a wave to complete one oscillation, measured in s

Transverse Waves: particles oscillate perpendicular to the direction of wave propagation, e.g., light waves
Longitudinal Waves: particles oscillate parallel to the direction of wave propagation, e.g., sound waves

Superposition: overlapping of two or more waves resulting in a new wave pattern
Constructive Interference: waves combine to form a wave with increased amplitude
Destructive Interference: waves combine to form a wave with decreased amplitude

Mechanical Waves require a physical medium to propagate, examples include water waves and sound waves.
Electromagnetic Waves do not require a physical medium, examples include light, radio waves, and X-rays.

Amplitude is the maximum displacement of a wave from its equilibrium position.
Wavelength is the distance between two consecutive points on a wave that are in phase.
Frequency is the number of oscillations or cycles per second, measured in Hz (Hertz).
Speed is the distance traveled by a wave per unit time, measured in m/s (meters per second).
Period is the time taken by a wave to complete one oscillation, measured in s (seconds).

Transverse Waves are waves in which particles oscillate perpendicular to the direction of wave propagation, example: light waves.
Longitudinal Waves are waves in which particles oscillate parallel to the direction of wave propagation, example: sound waves.

Superposition occurs when two or more waves overlap, resulting in a new wave pattern.
Constructive Interference occurs when waves combine to form a wave with increased amplitude.
Destructive Interference occurs when waves combine to form a wave with decreased amplitude.
