Wave
A material that allows light to pass through completely
The bending of light when it passes from one material to another.
A material that does not allow light to pass through.
A disturbance that transfers energy from one place to another.
Refraction
A material that allows light to pass through completely.
The speed at which a wave travels through a medium
The bending of light when it passes from one material to another
The spreading out of waves as they move around a barrier or through an opening
Opaque
A material in which light does not pass through
A material that allows some light to pass through but not completely
A material that allows light to pass through completely
The spreading out of waves once they hit a barrier or an opening
Transparent + (choose an example)
A material that does allow light to pass through but not completely
PNG. It is called png because when inputting inside a program (e.g. CapCut or Ibispaintx) the background is invisible only the object itself.
Air, Air contains mass and particles which the sunlight is partially blocked from reaching the ground
A material that does allow light to pass through completely
Reflection
A material that does not allow light to pass through
The bouncing back of a wave when it hits a surface it cannot pass through
The material at which through a wave travels
A disturbance that transfers energy from one place to another
Wave speed
The number of waves that passes through in a given time
The speed at which a wave travels through a medium
The distance between two corresponding points on a wave, such as crest to crest.
The spreading out of waves as they move around a barrier or through an opening.
What is Diffraction?
The bending of light when it passes from one material to another.
The distance between two corresponding points on a wave, such as crest to crest.
The spreading out of waves as they move around a barrier or through an opening.
The bouncing back of a wave when it hits a surface it cannot pass through.
The distance between one crest and the next crest of a wave is called the
(a)
Light as it passes through water is an example of
(a)
The height of a wave is its _, which is related to the wave's energy.
(a)
As the wavelength of a wave increases, the frequency:
Increases
Decreases
Remains the same
Increases, then decreases
Which wave interaction explains why sound waves can be heard around corners?
Reflection
Refraction
Diffraction
Absorption
Refraction occurs when a wave enters a new medium at an angle because:
The frequency changes
The amplitude changes
The wave speed changes
None of the above.

Waves transfer:
Matter
Energy
Particles
Mass
A wave that is a combination of both a longitudinal and a transverse wave is called a:
Sound wave
Light wave
Rope wave
Surface wave
During constructive interference:
The amplitude increases
The frequency decreases

Which type of wave does NOT require a medium to travel?
Electromagnetic waves
Longitudinal waves
Surface waves
Mechanical waves
A longitudinal wave is a wave in which particles of the medium move:
Perpendicular to the wave's direction
Parallel to the wave's direction
At an angle to the wave's direction
In circular motion
A transverse wave is a wave in which particles move:
In circular motion
Parallel to the wave's direction
Perpendicular to the wave's direction
In random directions
