Final Review

Front

What happens to a ray through the focus of a spherical mirror when it is reflected?

Back

It is reflected parallel to the optical axis.

Front

What is an example of a discrete quantity?

Back

The total static charge on a sock fresh out of the dryer.

Front

Why does the twin 'paradox' appear to be a paradox?

Back

Because they cannot both be younger than the other.

Front

What is the resolution of the Barn (apparent) paradox?

Back

The pole fits and it doesn't fit.

Front

Which type of mirror can magnify?

Back

Concave mirror.

Front

Define a concave mirror.

Back

A mirror that curves inward and can magnify images.

Front

What is the principle of reflection in optics?

Back

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

Front

Explain the concept of discrete vs continuous quantities.

Back

Discrete quantities can only take specific values, while continuous quantities can take any value within a range.

Front

What is the significance of the optical axis in mirror reflection?

Back

It is the line that defines the symmetry of the mirror and the path of light rays.

Front

Describe the concept of time dilation in the context of the twin paradox.

Back

Time dilation occurs when one twin travels at a high speed, causing them to age slower than the twin who remains stationary.
