Intro to Waves & Wave Calculations

What is the significance of the wave equation?

• It describes the relationship between wave speed, frequency, and wavelength, allowing us to understand wave behavior.

• It explains the principles of quantum mechanics and particle behavior.

• It provides a formula for calculating the energy of a wave based on its amplitude.

• It outlines the historical development of wave theory in physics.

What is the definition of a trough in a wave?

• A trough is the highest point of a wave.

• A trough is the lowest point of a wave.

• A trough is the distance between two waves.

• A trough is the speed of a wave.

If a wave has a frequency of 20 Hz and a wavelength of 2.5 m, how fast is it traveling?

• 30 m/s

• 40 m/s

• 50 m/s

• 60 m/s

What is the definition of wavelength?

• Wavelength is the distance between two consecutive crests or troughs in a wave.

• Wavelength is the speed at which a wave travels through a medium.

• Wavelength is the amplitude of a wave measured from the equilibrium position.

• Wavelength is the frequency of a wave multiplied by its speed.

What is a wave?

• A wave is a disturbance that transfers energy from one place to another without transferring matter.

• A wave is a solid object that moves through space.

• A wave is a type of particle that carries mass.

• A wave is a stationary phenomenon that does not involve energy transfer.

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

• The wavelength increases.

• The wavelength decreases.

• The wavelength remains the same.

• The wavelength becomes unpredictable.

What is the definition of a crest in a wave?

• A crest is the highest point of a wave.

• A crest is the lowest point of a wave.

• A crest is the distance between two waves.

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

What is amplitude in a wave?

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

• Amplitude is the frequency of the wave measured in hertz.

• Amplitude is the speed at which the wave travels through a medium.

• Amplitude is the total energy carried by the wave.

What is the relationship between wave speed, frequency, and wavelength?

• Wave speed (v) is equal to the product of frequency (f) and wavelength (λ): v = f × λ.

• Wave speed (v) is the sum of frequency (f) and wavelength (λ): v = f + λ.

• Wave speed (v) is equal to the difference between frequency (f) and wavelength (λ): v = f - λ.

• Wave speed (v) is inversely proportional to frequency (f) and wavelength (λ): v = 1/(f × λ).

What is the difference between transverse and longitudinal waves?

• In transverse waves, the particle movement is parallel to the direction of wave travel, while in longitudinal waves, the particle movement is perpendicular to the direction of wave travel.

• In transverse waves, the particle movement is perpendicular to the direction of wave travel, while in longitudinal waves, the particle movement is parallel to the direction of wave travel.

• Transverse waves can travel through solids only, while longitudinal waves can travel through both solids and liquids.

• Transverse waves have a higher frequency than longitudinal waves.
