Flashcards on Wave Interactions

Click on the flashcard to see the answer


What is wave interference?

When two or more waves meet and combine

What are the two types of wave interference?

Constructive and destructive interference

Define constructive interference.

When two waves combine to form a larger amplitude

Define destructive interference.

When two waves combine to form a smaller or zero amplitude

What is a standing wave?

A wave that appears to stay in one place because the interference of the original wave and its reflected wave create points of constructive and destructive interference

What is reflection of waves?

When waves bounce off a surface

What is refraction of waves?

When waves change direction as they pass through different materials

What is diffraction of waves?

When waves bend or spread out as they pass through an opening or around obstacles

What is absorption of waves?

When waves are absorbed by a material and converted into other forms of energy

What is transmission of waves?

When waves pass through a material or medium

Give an example of constructive interference.

When two water waves meet and create a larger wave

Give an example of destructive interference.

When a sound wave meets its exact opposite sound wave and cancels out

How does refraction of waves contribute to the bending of light?

When light waves pass through different media, they experience a change in speed and bend or refract

What happens when a wave reaches a boundary and is partially reflected and partially transmitted?

Some of the wave's energy is reflected and some is transmitted to the new medium

What is the effect of increasing the amplitude of a wave?

The wave becomes more intense and carries more energy
