T3 Unit 2: S3 - Refraction

TRUE or FALSE.

Refraction occurs when light bends as it meets the surface of two mediums with different densities.

• TRUE

• FALSE

TRUE or FALSE.

The medium with a lower refractive index would have a higher angle of refraction.

• TRUE

• FALSE

TRUE or FALSE.

The emergent ray will always have the same angle as that of the incident ray.

• TRUE

• FALSE

TRUE or FALSE.

The Snell's Law states that the refractive index of the incident ray is inversely proportional to its angle.

• TRUE

• FALSE

TRUE or FALSE.
