A device that produces an image from light that enters it.

An empty, closed box with a tiny hole on the front face and a screen on the back face.

Describes a material that lets some light through, but through which objects cannot be seen clearly.

A pinhole camera

In the Waves unit, they will build on this knowledge to learn about the properties and propagation of transverse and longitudinal waves.

In the Sound, light and vision unit, pupils learnt how sound waves travel through different types of medium and are absorbed and reflected, how light is reflected off mirrors, and how the eye can see objects by the light they reflect.

This unit explores the transmission of light, including absorption, scattering, and reflection, and the use of the ray model in imaging, refraction, and lenses. It also covers energy transfer in various processes, using safe techniques, making accurate observations, and improving reliability.

Which of the following are needed for a pinhole camera to show a clear image?

A pupil makes a pinhole camera and uses it to make an image of a bulb. Then the pupil makes the pinhole larger. In which of the following ways does this change the image?

using a longer box for the pinhole camera

using a shorter box for the pinhole camera

A pinhole camera makes an image of a filament bulb. Which of the following changes will make the image smaller?

An image of the bulb fits through the pinhole and lands on the screen.

The pinhole changes the directions of rays so that they make an image.

Each point on the screen is hit by light from every point on the bulb.

Each point on the screen is hit by light from only one point on the bulb.

A pupil holds up a pinhole camera at a short distance from a filament bulb that is switched on. Which of the following statements explains why an image of the bulb appears on the screen?

It lets light through and you can see clearly through it.

It lets light through and changes the colour of the light.

It lets some light through, but you cannot see clearly through it.

Which of the following is a definition of a translucent material?

an object that reflects light the way a mirror does

Which of the following describes a luminous object?

In diagrams, we can draw arrows to show the direction light travels, and where the light travels from and to. What are these arrows called?

Which of the following is a definition of the word ‘image’?

Light from the surroundings must hit the object.

Light coming from your eyes must enter the object.

Light coming from the object must enter your eyes.

Which of the following statements is always necessary for you to be able to see an object?

The lamp’s light and the daylight cancel each other out.

The lamp produces more light when its surroundings are dark.

There is more contrast between the lamp and its surroundings at night.

More of the lamp’s light is absorbed by the surroundings during the day.

Which of the following statements explains why it is easier to see a dim lamp outdoors at night than in the day?
