Light Behavior and Properties Assessment

The video tutorial explores how light behaves, focusing on absorption, scattering, and refraction. It includes experiments with water, dye, milk, and gummy bears to demonstrate these concepts. The tutorial also introduces absorption spectra and encourages problem-solving. Real-life applications of refraction are shown using prisms and water. Resources for further exploration are provided.

What happens when a torch is shone through plain water?

• The light is absorbed completely.

• The light changes color.

• The light travels straight through.

• The light is scattered in all directions.

What effect does adding blue food coloring to water have on light?

• It absorbs all colors except blue.

• It reflects all colors.

• It scatters the light.

• It makes the light invisible.

How does milk affect the behavior of light?

• It changes the color of the light.

• It scatters the light due to fat globules.

• It allows light to pass through without any change.

• It absorbs all the light.

What is the purpose of an absorption spectra?

• To measure the speed of light.

• To indicate which colors are absorbed and which are visible.

• To demonstrate the bending of light.

• To show how light is scattered.

What does a prism demonstrate about light?

• Light travels in a straight line.

• Light can be split into its component colors.

• Light cannot pass through glass.

• Light can be absorbed by all materials.

How can refraction be demonstrated using everyday items?

• By using a metal rod.

• By using a torch and a mirror.

• By using a glass of water.

• By using a piece of paper.

What happens when red light is shone on a red gummy bear?

• The light is absorbed completely.

• The light is reflected back.

• The light passes through easily.

• The light changes to green.

Why does a green gummy bear not allow red light to pass through?

• Because it changes the light to blue.

• Because it absorbs the red light.

• Because it is transparent.

• Because it reflects all colors.

What is the main learning objective of the gummy bear experiment?

• To see how different colors of light are absorbed by different materials.

• To demonstrate the bending of light.

• To understand how light is scattered.

• To measure the speed of light.

Where can students find additional resources related to the light experiments?

• In the school library.

• On a social media platform.

• On the Royal Academy of Engineering STEM resource hub.

• In the local bookstore.
