Heat flash

The video tutorial demonstrates how energy in the form of light is absorbed and reflected by different surfaces. A bright camera flash is used to show how black ink absorbs energy, leading to vaporization and smoke, while white paper reflects most of the energy, resulting in less dramatic effects.

What is the primary form of energy released by the camera flash?

• Sound

• Heat

• Electricity

• Light

Why does black ink on newspaper create a smoke cloud when exposed to a camera flash?

• It cools down rapidly.

• It absorbs a lot of energy, causing vaporization.

• It reflects the light energy.

• It changes color.

Which area of the newspaper absorbs more energy from the flash?

• White area

• Black area

• Both absorb equally

• Neither absorbs energy

What happens to the energy when it hits the white areas of the newspaper?

• It is mostly reflected.

• It causes the paper to burn.

• It is absorbed completely.

• It changes the color of the paper.

What is the result of the energy being mostly reflected by the white paper?

• The paper becomes transparent.

• The effect is less dramatic.

• The paper changes color.

• The paper catches fire.
