Wave Properties and Behavior

This video tutorial covers wave interactions, including reflection, refraction, diffraction, and absorption. It explains the differences between mechanical and electromagnetic waves, emphasizing the need for a medium in mechanical waves. The tutorial further breaks down mechanical waves into transverse and longitudinal types, illustrating their movement with examples. The lesson concludes with instructions for a lab activity using slinkys to model wave behavior.

What happens to a wave when it encounters a surface it cannot pass through?

• It gets absorbed.

• It stops completely.

• It reflects back.

• It speeds up.

According to the law of reflection, how does a wave reflect off a surface?

• It does not reflect.

• At the same angle it hits the surface.

• At a 90-degree angle.

• At a random angle.

What causes a wave to refract?

• A change in the wave's direction.

• A change in the wave's amplitude.

• A change in the wave's medium.

• A change in the wave's frequency.

When light passes through a prism, what phenomenon occurs?

• Reflection

• Refraction

• Absorption

• Diffraction

What is diffraction?

• The absorption of waves by a surface.

• The bending of waves around obstacles.

• The reflection of waves off a surface.

• The speeding up of waves in a medium.

Which type of wave requires a medium to travel through?

• Neither type

• Both types

• Electromagnetic waves

• Mechanical waves

How do transverse waves move?

• The wave and pulses move in the same direction.

• The wave moves left to right, pulses move up and down.

• The wave moves up and down, pulses move left to right.

• The wave and pulses move in opposite directions.

What is a characteristic of longitudinal waves?

• Pulses move perpendicular to wave direction.

• Pulses do not move.

• Pulses move in a circular pattern.

• Pulses move parallel to wave direction.

Which of the following is an example of a transverse wave?

• Water wave

• Sound wave

• Light wave

• Seismic wave

What is the main difference between mechanical and electromagnetic waves?

• Mechanical waves require a medium.

• Electromagnetic waves require a medium.

• Electromagnetic waves cannot travel through empty space.

• Mechanical waves can travel through empty space.
