The video explains how mechanical waves can be modeled and introduces the concept of light waves being represented as two waves moving at right angles to each other.

What type of wave is represented by the movement described in the video?

• Gravitational wave

• Mechanical wave

• Electromagnetic wave

• Sound wave

Which of the following is NOT a characteristic of a mechanical wave?

• Requires a medium to travel

• Can travel through a vacuum

• Can be longitudinal or transverse

• Transfers energy through a medium

How can a light wave be modeled according to the video?

• As two waves moving in parallel

• As two waves moving at right angles

• As a circular wave

• As a single wave

What is the orientation of the two waves in a light wave model?

• Parallel to each other

• At right angles to each other

• In the same direction

• Opposite to each other

Which type of wave can be modeled as two waves moving at right angles?

• Water wave

• Light wave

• Mechanical wave
