Exit Ticket Light (11/6)

Front

What is the principle of light reflection?

Back

Light reflection is the bouncing back of light rays when they hit a surface. This can cause images to appear in surfaces like water.

Front

How does light behave when it hits a smooth surface like water?

Back

When light hits a smooth surface like water, it reflects at the same angle at which it strikes the surface, following the law of reflection.

Front

What is refraction in the context of light?

Back

Refraction is the bending of light as it passes from one medium to another, such as from air to water, which can cause objects to appear displaced.

Front

Why do objects appear distorted when viewed through water?

Back

Objects appear distorted when viewed through water due to the refraction of light, which changes the direction of light rays as they move from water to air.

Front

What causes the apparent depth of an object in water to differ from its actual depth?

Back

The apparent depth differs from actual depth due to the refraction of light, which makes the object seem closer to the surface than it really is.

Front

What is the law of reflection?

Back

The law of reflection states that the angle of incidence is equal to the angle of reflection.

Front

How does the angle of incidence affect the reflection of light?

Back

The angle of incidence determines how light will reflect off a surface; a steeper angle of incidence results in a steeper angle of reflection.

Front

What is total internal reflection?

Back

Total internal reflection occurs when light attempts to move from a denser medium to a less dense medium at an angle greater than the critical angle, causing it to reflect entirely back into the denser medium.

Front

What role does the surface texture play in light reflection?

Back

The surface texture affects how light is reflected; smooth surfaces produce clear reflections, while rough surfaces scatter light.

Front

How can light reflection be observed in nature?

Back

Light reflection can be observed in nature through phenomena such as the reflection of trees in a lake or the shimmering of light on water.
