Waves

What is constructive interference?

• Constructive interference occurs when two waves meet in phase, resulting in a wave of greater amplitude.

• Constructive interference occurs when two waves are out of phase, canceling each other out.

• Constructive interference occurs when two waves travel in opposite directions.

• Constructive interference occurs when two waves have different frequencies, resulting in a beat frequency.

What is the relationship between frequency and wavelength?

• Frequency and wavelength are directly related; as frequency increases, wavelength also increases.

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

• Frequency and wavelength have no relationship; they are independent of each other.

• Frequency and wavelength are equal; they represent the same physical quantity.

What is reflection in wave behavior?

• Reflection is when a wave bounces off an object instead of passing through it.

• Reflection is when a wave continues to travel in the same direction without changing.

• Reflection is the process of a wave being absorbed by an object.

• Reflection is when a wave splits into two different waves upon hitting an object.

What is refraction?

• The bending of a wave as it passes from one medium to another, caused by a change in speed.

• The reflection of light when it hits a surface at an angle.

• The absorption of light by a medium, preventing it from passing through.

• The scattering of light in different directions as it passes through a medium.

What is the frequency of a wave?

• The speed of the wave in meters per second.

• The distance between two consecutive waves.

• The number of waves that pass a given point in one second, measured in Hertz (Hz).

• The amplitude of the wave measured in decibels.

What is diffraction?

• Diffraction is the bending of waves around obstacles or through openings.

• Diffraction is the reflection of waves off surfaces.

• Diffraction is the absorption of waves by materials.

• Diffraction is the scattering of waves in different directions.

What is the difference between transverse and compressional waves?

• Transverse waves move parallel to the direction of the wave, while compressional waves move perpendicular to the direction of the wave.

• Transverse waves move in a circular motion, while compressional waves move in a straight line.

• Transverse waves move perpendicular to the direction of the wave, while compressional waves move parallel to the direction of the wave.

• Transverse waves are slower than compressional waves, which are faster.

What happens to a wave's speed when it enters a different medium?

• The speed of the wave remains constant regardless of the medium.

• The speed of the wave changes depending on the properties of the new medium.

• The speed of the wave increases in all mediums.

• The speed of the wave decreases in all mediums.

What type of waves are sound waves?

• Transverse waves

• Electromagnetic waves

• Compressional waves

• Surface waves

What is destructive interference?

• A phenomenon where two waves meet in phase, resulting in a wave of greater amplitude.

• Destructive interference occurs when two waves meet out of phase, resulting in a wave of lesser amplitude or cancellation.

• A type of interference that only occurs with sound waves.

• An effect that amplifies the sound of waves when they overlap.
