Comprehensive Wave Physics: Types, Properties, and Behaviors

What is the physics definition of a wave?

A vibration or oscillation that transfers energy.

What are mechanical waves?

Wave motion that requires a medium (e.g., water, sound).

What are electromagnetic waves?

Waves that do not require a medium (e.g., light, radio waves).

What are matter waves?

Waves that show wave-like behavior of particles like electrons under certain conditions.

What type of wave is a transverse wave?

A wave where the medium is displaced perpendicular to the direction of the wave.

What type of wave is a longitudinal wave?

A wave where the medium is displaced parallel to the direction of the wave.

What are surface waves?

Waves where the medium is displaced both perpendicular and parallel to the direction of the wave.

What is the crest of a wave?

The highest displacement from the line of equilibrium.

What is the trough of a wave?

The lowest displacement from the line of equilibrium.

What does amplitude refer to in wave properties?

The displacement from the line of equilibrium to the height of a crest or trough.

What is frequency in the context of waves?

The number of waves that pass a given point in a second.

What is wave speed?

The speed at which a wave travels through a medium, dependent solely on the properties of the medium.

What is wavelength?

The shortest distance between points of a wave where the wave pattern repeats itself.

What happens to a wave at a boundary between two media?

A portion of its energy is transmitted into the new medium, and a portion is reflected.

What is the Law of Reflection?

The angle of incidence equals the angle of reflection.

What is refraction?

The change in direction of waves as they pass from one medium to another.

What is diffraction?

The bending of waves around a barrier.

What is constructive interference?

When two waves meet and their displacements add together to form a larger wave.

What is destructive interference?

When two waves meet and their displacements cancel each other out.

What is a standing wave?

A pattern resulting from the interference of two or more waves along the same medium.

What are nodes in a standing wave?

Points of no displacement in a standing wave pattern.

What are antinodes in a standing wave?

Positions of maximum displacement in a standing wave pattern.

How does sound travel?

Sound travels through a medium (solid, liquid, or gas) by pushing particles of the substance.

What determines the loudness of a sound?

Loudness depends on the amplitude of the sound wave.

What is the relationship between wave speed, frequency, and wavelength?

Wave speed is the product of frequency and wavelength.

What is the speed of electromagnetic waves in a vacuum?

3.00 x 10^8 m/s, commonly represented by the symbol c.

What happens to the frequency of a wave when it crosses a boundary?

The frequency remains constant.
