PHYSCIE REVIEWER

In what ways can light’s behavior be described?

• Curve and linear motions
• . Projectile motion
• Waves and particles
• Waves and shadows

How does refraction happen when light rays travel in a straight line from air until it encounters another medium like water?

• a.The speed of light will be slower as it enters the water, making the angle of refraction (θr) smaller than the angle of incidence (θi).
• b. The angle of refraction (θr) will be bigger than the angle of incidence (θi) because light will travel faster as it enters the water.
• c. Light rays will refract at a smaller angle because light rays will travel faster in water.
• d. Light rays will refract at a bigger angle because light rays will travel slower in water

• A
• B
• C
• D

A light ray passes from water into the air. The angle that the light makes with the normal is 44 degrees. The indices of refraction for both water and air are given in the diagram. What angle does the light ray make with the normal as it approaches the boundary from the water?

• A
• B
• C
• D

When illustrating a ray diagram, you can draw the mirrored image by using at least ___.

• 2 lines
• 3 lines
• 4 lines
• 5 lines

What principle is responsible when we see yellow to red skies in the early morning or late afternoon?

• Diffraction
• Reflection
• Interference
• Scattering

Emma is swimming in a pool and notices that her legs appear bent at the water's surface. Which model, the wave model or the particle model, can best explain this phenomenon of apparent bending?

• The wave model, as it explains the refraction of light waves as they pass from water to air, causing the apparent bending.
• The particle model, as it explains the interaction of photons with the water molecules, causing them to change direction.
• Both models are equally valid and explain different aspects of refraction.
• None of the models can fully explain the phenomenon of apparent bending

David is looking at himself in a mirror. What model, the wave model or the particle model, can best explain the phenomenon of seeing a reflection?

• The wave model, as it explains the reflection of light waves from the smooth surface of the mirror.
• The particle model, as it explains the interaction of photons with the atoms in the mirror, causing them to bounce back.
• Both models are equally valid and explain different aspects of reflection.
• None of the models can fully explain the phenomenon of reflection.

What is the reflection of light?

• The bending of light as it passes through a medium with different optical densities.
• The change in direction of light when it travels from one medium to another.
• The bouncing back of light from a surface without changing its medium.
• The interference of light waves results in a cancellation of light intensity

• The change in direction of light when it travels from one medium to another.
