Light Exit Ticket 11/4

Front

What is the behavior of light when it encounters a transparent object?

Back

Light passes through transparent objects with little to no scattering.

Front

What happens to light when it hits a reflective surface?

Back

Light bounces off reflective surfaces, following the law of reflection.

Front

Define refraction in the context of light behavior.

Back

Refraction is the bending of light as it passes from one medium to another due to a change in speed.

Front

What is the law of reflection?

Back

The angle of incidence is equal to the angle of reflection.

Front

How does light behave when it encounters an opaque object?

Back

Light is absorbed or blocked by opaque objects, preventing it from passing through.

Front

What is the difference between diffuse reflection and specular reflection?

Back

Diffuse reflection scatters light in many directions, while specular reflection reflects light in a single direction.

Front

What is the index of refraction?

Back

The index of refraction is a measure of how much light slows down in a medium compared to its speed in a vacuum.

Front

Explain 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 is the critical angle in optics?

Back

The critical angle is the angle of incidence above which total internal reflection occurs.

Front

How does the color of an object affect the light it reflects?

Back

An object's color is determined by the wavelengths of light it reflects; for example, a red object reflects red wavelengths and absorbs others.
