Wave Behavior: Reflection, Refraction, and Interference Explained

Coach Spivey and his son Jordan present a tutorial on wave behavior, covering reflection, refraction, diffraction, wave interference, and standing waves. They explain each concept with examples, emphasizing the importance of angles in reflection, the bending of waves in refraction, and the effects of wave interference. The tutorial concludes with a motivational message encouraging positivity and understanding.

What happens to a wave when it reflects off a surface?

• It gets absorbed by the surface.

• It changes its speed.

• It changes its frequency.

• It maintains the same angle of incidence and reflection.

Why does a pencil appear bent when placed in a glass of water?

• The pencil is actually bent.

• The air around the pencil is denser.

• Light waves slow down in water, causing refraction.

• The water distorts the pencil's shape.

What determines the extent of diffraction of a wave?

• The temperature of the medium.

• The wavelength and size of the opening.

• The speed of the wave.

• The color of the wave.

How does the wavelength affect diffraction?

• Shorter wavelengths diffract more.

• Longer wavelengths diffract less.

• Wavelength does not affect diffraction.

• Longer wavelengths diffract more.

What is constructive interference?

• When a wave bends around an object.

• When two waves combine to form a larger wave.

• When two waves cancel each other out.

• When a wave reflects off a surface.

What is destructive interference?

• When two waves combine to form a larger wave.

• When two waves pass through each other without interaction.

• When two waves combine to form a smaller wave.

• When a wave bends as it enters a new medium.

What happens when two waves meet and are in phase?

• They form a larger wave.

• They form a smaller wave.

• They cancel each other out.

• They pass through each other unchanged.

What is a node in a standing wave?

• A point where the wave changes direction.

• A point where the wave is at rest.

• A point of maximum energy.

• A point of minimum wavelength.

What is an antinode in a standing wave?

• A point of maximum energy.

• A point where the wave is at rest.

• A point of no energy.

• A point where the wave changes direction.

What is the main characteristic of a standing wave?

• It travels through the medium.

• It appears to stay in one place.

• It reflects off surfaces.

• It changes frequency constantly.
