Topic 3 Lesson 2 Patterns of Waves

Front

What is a plane wave?

Back

A plane wave is a wave that travels in parallel lines and has a constant phase across any plane perpendicular to the direction of propagation.

Front

What characteristic describes a plane wave?

Back

A plane wave begins with a line.

Front

What type of wave pattern is created when a drop reaches the water?

Back

A circular wave pattern is created.

Front

How does a wave created by Jana move?

Back

The wave starts at a single point and moves outward in all directions.

Front

What is the movement direction of a plane wave?

Back

A plane wave moves in one direction.

Front

What is a wave?

Back

A wave is a disturbance that transfers energy from one place to another without transferring matter.

Front

What is the difference between a circular wave and a plane wave?

Back

A circular wave spreads out in circles from a point, while a plane wave travels in straight lines.

Front

What happens to the speed of a wave as it approaches the edge of a dish?

Back

The wave may increase its speed as it gets closer to the edge.

Front

What is the definition of wavelength?

Back

Wavelength is the distance between two consecutive points that are in phase on a wave, such as crest to crest.

Front

What is frequency in relation to waves?

Back

Frequency is the number of waves that pass a point in one second.
