Unit 4 - Waves

Front

What are waves?

Back

Waves are disturbances that transfer energy from one place to another without transferring matter.

Front

What types of mediums can waves travel through?

Back

Waves can travel through solids, liquids, gases, and even empty space.

Front

What is energy transfer in waves?

Back

All waves transfer energy, which can be in the form of sound, light, or heat.

Front

What is wavelength?

Back

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

Front

What is frequency?

Back

Frequency is the number of waves that pass a given point in one second, measured in Hertz (Hz).

Front

What is amplitude?

Back

Amplitude is the maximum displacement of points on a wave from its rest position, indicating the energy of the wave.

Front

What is the difference between mechanical and electromagnetic waves?

Back

Mechanical waves require a medium to travel through, while electromagnetic waves can travel through a vacuum.

Front

What is refraction?

Back

Refraction is the bending of waves as they pass from one medium to another due to a change in speed.

Front

What is reflection?

Back

Reflection is the bouncing back of waves when they hit a barrier or surface.

Front

What is the electromagnetic spectrum?

Back

The electromagnetic spectrum is the range of all types of electromagnetic radiation, from radio waves to gamma rays.
