FLASHCARD QUESTION

Front

Wave Noun

[wayv]

Back

Wave


A repeating disturbance pattern that transfers energy from one location to another without transferring any matter.

Example: This diagram shows a wave and labels its key parts: the highest point (crest), the lowest point (trough), its height (amplitude), and its length (wavelength).

FLASHCARD QUESTION

Front

Wavelength Noun

[wayv-length]

Back

Wavelength


The distance between two corresponding points on a repeating wave, such as the distance from one crest to the next.

Example: This diagram shows a wave and labels the wavelength as the distance from the top of one wave (crest) to the top of the next.

FLASHCARD QUESTION

Front

Refract Verb

[ri-frakt]

Back

Refract


To bend a wave as it passes from one medium to another due to a change in its speed.

Example: When light travels from air into water, it bends, making the straws in the glass look broken or bent at the water's surface.

FLASHCARD QUESTION

Front

Absorb Verb

[ab-sorb]

Back

Absorb


To take in energy, such as light, which is then often converted into another form like thermal energy.

Example: A plant's roots absorb water from the soil, and its leaves absorb sunlight and carbon dioxide from the air to make food.

FLASHCARD QUESTION

Front

Reflect Verb

[ri-flekt]

Back

Reflect


To bounce a wave, such as light, off the surface of a material, causing it to change direction.

Example: A light ray from a source hits a mirror and bounces off, showing how the angle of incidence equals the angle of reflection.

FLASHCARD QUESTION

Front

Transmit Verb

[trans-mit]

Back

Transmit


To allow a wave, such as light, to pass through a material without being absorbed or reflected.

Example: Moving a spring up and down transmits energy along its length, creating a wave that travels from the hand to the wall.

FLASHCARD QUESTION

Front

Energy Noun

[en-er-jee]

Back

Energy


The capacity to do work or cause change, which can be transferred between objects or converted into different forms.

Example: A diver has potential energy on the board, which converts to kinetic energy (the energy of motion) as they fall towards the water.
