A student observes that a flashlight does not turn on. What could be a possible reason based on the requirements for a functioning circuit?

• The battery is not connected properly, creating an open circuit.

• The light bulb is too bright.

• The switch is in the off position, creating a closed circuit.

• The flashlight is too old.

A beam of light hits a mirror at an angle. Predict what will happen to the light beam.

• The light beam will be absorbed by the mirror.

• The light beam will pass through the mirror.

• The light beam will be reflected off the mirror at the same angle.

• The light beam will be refracted by the mirror.
