Wave Behavior and Interference Concepts

The video tutorial covers wave behaviors, including reflection, refraction, diffraction, and interference. It explains how waves interact with surfaces, change direction in different media, bend around obstacles, and overlap to form new waves. The tutorial includes examples and encourages students to take notes and watch supplementary videos for deeper understanding.

What is the law of reflection?

• Waves combine to form a new wave.

• Waves spread out after passing through a gap.

• Waves bend when they pass through different media.

• Waves bounce off a surface at an angle equal to the angle of incidence.

What is a normal line in the context of wave reflection?

• A line that divides the wave into two equal parts.

• A line that represents the wave's amplitude.

• An imaginary line at right angles to a surface.

• A line parallel to the surface.

What happens to light when it enters a more dense medium?

• It slows down and bends towards the normal.

• It speeds up and bends away from the normal.

• It maintains its speed and direction.

• It reflects back into the original medium.

Which of the following best describes refraction?

• The bouncing of waves off a surface.

• The bending of waves as they pass from one medium to another.

• The spreading of waves after passing through a gap.

• The combination of two or more waves to form a new wave.

What is diffraction?

• The bending of waves around an obstacle.

• The refraction of waves through a medium.

• The reflection of waves off a surface.

• The interference of two waves.

In which scenario does diffraction occur?

• When waves pass through a gap in an obstacle.

• When waves encounter a complete obstacle.

• When waves pass through a perfectly flat surface.

• When waves are absorbed by a medium.

What is interference in wave behavior?

• The spreading of waves after passing through a gap.

• The reflection of waves off a surface.

• The bending of waves as they pass through different media.

• The combination of two or more waves to form a new wave.

What is constructive interference?

• When two waves cancel each other out.

• When two waves combine to form a larger wave.

• When waves bend around an obstacle.

• When waves reflect off a surface.

What happens during destructive interference?

• Waves bend around an obstacle.

• Waves combine to form a larger wave.

• Waves reflect off a surface.

• Waves cancel each other out.

Which type of interference results in a smaller amplitude?

• Diffraction

• Constructive interference

• Refraction

• Destructive interference
