What is wavelength?

• The time it takes for one complete wave cycle to pass a point.

• The distance between two consecutive peaks or troughs in a wave.

• The speed of the wave divided by its frequency.

• The amplitude of the wave measured from the rest position.

What is the relationship between wavelength and wave speed?

• Wave speed is equal to frequency multiplied by wavelength.

• Wavelength is equal to wave speed divided by frequency.

• Wave speed is independent of frequency and wavelength.

• Wavelength increases as wave speed increases.

What does it mean if a wave is described as 'longer' in wavelength?

• A longer wavelength means the distance between consecutive peaks is greater, resulting in lower frequency.

• A longer wavelength means the wave travels faster through a medium.

• A longer wavelength indicates a higher frequency of the wave.

• A longer wavelength means the wave has more energy.

What is amplitude in a wave?

• The frequency of the wave

• The maximum distance that points on a wave move from their rest position, indicating the energy of the wave.

• The speed at which the wave travels

• The wavelength of the wave

What happens to wave properties when energy is added?

• The wave's speed decreases and its amplitude remains constant.

• The wave's amplitude increases, and it may also affect the frequency and wavelength.

• The wave's frequency decreases and its wavelength increases.

• The wave's energy is absorbed and does not affect its properties.

What is the principle of superposition in waves?

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

• The principle of superposition states that waves can only exist independently without interaction.

• The principle of superposition states that waves can cancel each other out completely when they overlap.

• The principle of superposition states that the speed of a wave is determined by its frequency and wavelength.

What is the difference between a crest and a trough in a wave?

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

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

• A crest is the point where the wave starts, while a trough is where it ends.

• A crest and a trough are the same point in a wave.

How can you visually represent waves?

• Waves can be represented using graphs that show the height of the wave (amplitude) over time or distance.

• Waves can be represented using sound waves that are played back in real-time.

• Waves can be represented using physical models made of rubber bands.

• Waves can be represented using color-coded maps that show temperature variations.

What are the two main types of waves?

• Mechanical waves and sound waves

• Mechanical waves and electromagnetic waves

• Electromagnetic waves and seismic waves

• Mechanical waves and radio waves

What is a medium in the context of waves?

• A medium is a type of wave.

• A medium is the substance through which a wave travels, such as air, water, or solid materials.

• A medium is a measurement of wave frequency.

• A medium is the speed at which a wave travels.
