Unit 3-Waves

A _____ wave is a wave that travels from one location to another, transferring energy as it moves.

progressive

In a _____ wave, the wave does not transfer energy from one place to another; it oscillates in a fixed position.

stationary

The points of maximum displacement in a stationary wave are called _____ points.

antinode

The points of zero displacement in a stationary wave are known as _____ points.

node

Progressive waves can be classified into two main types: _____ and longitudinal waves.

transverse

A _____ wave is characterized by particle displacement parallel to wave propagation.

longitudinal

An example of a transverse wave is _____.

light waves

In a longitudinal wave, the regions of compressions and _____ alternate along the wave.

rarefactions

Sound waves travel as _____ waves through gases.

longitudinal

Transverse waves cannot travel through _____ mediums, only through solids and surfaces.

fluid

When two waves meet at the same point in space, their total displacement is the result of the principle of _____ of waves.

superposition

Stationary waves are formed when two waves of the same frequency and amplitude travel in _____ directions and interfere with each other.

opposite

The points in a stationary wave where the displacement is always zero are called _____ points.

nodes

The formation of a stationary wave is a result of _____ interference between two progressive waves.

constructive and destructive

In a stationary wave, the distance between two consecutive nodes is equal to half the _____ of the wave.

wavelength

Wave interference can be categorized into _____ and destructive interference.

constructive

When two crests meet, they form a _____ wave, resulting in increased amplitude.

larger

When a crest meets a trough, they can cancel each other out, leading to _____ interference.

destructive

The resulting wave from interference of multiple waves is called a _____ wave.

composite

The principle of _____ explains how waves superimpose when they meet.

superposition

Wave _____ is the bending of waves around obstacles and openings.

diffraction

The amount of _____ a wave experiences depends on its wavelength and the size of the obstacle.

diffraction

When waves pass through a narrow opening, they spread out in a _____ pattern.

circular

The phenomenon of wave diffraction is most noticeable when the opening is comparable in size to the _____ of the wave.

wavelength

Diffraction can occur with all types of _____, including sound, water, and light waves.

waves

Refraction is defined as the _____ of waves as they pass from one medium to another.

bending

When light travels from a denser medium to a rarer medium, it bends _____ the normal.

away from

The change in speed of light when it enters a new medium is due to the _____ index of the material.

refractive

At the boundary between two media, the angle of incidence and the angle of refraction are related by _____'s law.

Snell

The sin of the angle of incidence is to the sin of the angle of refraction as the _____ of the two media.

ratio of the velocities
