S8P4 Milestone Review

Front

What type of lens is a convex lens?

Back

A convex lens is a type of lens that is thicker in the middle than at the edges and converges light rays that are coming in parallel to its principal axis.

Front

What type of lens is a concave lens?

Back

A concave lens is a type of lens that is thinner in the middle than at the edges and diverges light rays that are coming in parallel to its principal axis.

Front

What happens to the wavelength of a wave when its frequency increases?

Back

When the frequency of a wave increases, the wavelength decreases.

Front

What is the path of a light ray entering a glass block from air?

Back

The path of the light ray will bend towards the normal as it enters the glass block due to refraction.

Front

What does one wavelength represent in terms of wave properties?

Back

One wavelength is the distance from one compression to the next compression in a wave.

Front

Define refraction.

Back

Refraction is the bending of light as it passes from one medium to another due to a change in its speed.

Front

What is the relationship between frequency and wavelength in waves?

Back

Frequency and wavelength are inversely related; as frequency increases, wavelength decreases.

Front

What is a ray diagram?

Back

A ray diagram is a visual representation used to show the path of light rays as they travel through different media.

Front

What is the principle of superposition in waves?

Back

The principle of superposition states that when two or more waves overlap, the resulting wave is the sum of the individual waves.

Front

What is the definition of amplitude in a wave?

Back

Amplitude is the maximum distance that points on a wave, such as the crest or trough, move from their rest position.
