MMM Topic 5 Lesson 1 y 2

Front

What is reflection in the context of waves?

Back

Reflection is the bouncing back of a wave when it hits a barrier or a surface.

Front

Define constructive interference.

Back

Constructive interference occurs when two waves meet and combine to form a wave with a larger amplitude.

Front

What is destructive interference?

Back

Destructive interference occurs when two waves meet and combine to form a wave with a smaller amplitude or cancel each other out.

Front

Explain the phenomenon of 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 a wavelength?

Back

Wavelength is the distance between successive crests or troughs of a wave.

Front

How does the amplitude of a wave affect its energy?

Back

The amplitude of a wave is directly related to its energy; higher amplitude means more energy.

Front

What is the relationship between frequency and wavelength?

Back

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

Front

What is the principle of superposition in wave theory?

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 difference between a crest and a trough?

Back

A crest is the highest point of a wave, while a trough is the lowest point.

Front

What happens to light when it passes through a prism?

Back

When light passes through a prism, it is refracted and dispersed into its component colors.
