General Wave Properties Quiz

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

• Speed = Frequency + Wavelength
• Speed = Frequency × Wavelength
• Speed = Wavelength / Frequency
• Speed = Frequency - Wavelength

Which of the following correctly describes a transverse wave?

• Vibrations are parallel to the direction of travel
• It consists of compressions and rarefactions
• Vibrations are at right angles to the direction of travel
• It cannot travel through a vacuum

When light enters a more optically dense medium, what happens to its speed and direction?

• Speed increases and bends away from the normal
• Speed decreases and bends towards the normal
• Speed remains the same and bends towards the normal
• Speed decreases and travels in a straight line

What is the critical angle in total internal reflection?

• The angle at which light is completely absorbed
• The angle at which light bends towards the normal
• The angle of incidence that results in no refraction
• The angle of incidence greater than which total internal reflection occurs

Which of the following statements about optical fibers is true?

• They use reflection to transmit sound
• They are made of metal
• They rely on total internal reflection to transmit light
• They can only transmit light in a straight line

What happens to the colors of light when it passes through a prism?

• They combine to form white light
• They split into a spectrum of colors
• They disappear
• They reflect back into the prism

Which electromagnetic wave has the highest frequency?

• Radio waves
• Microwaves
• X-rays
• Gamma rays

What is the primary characteristic of sound waves?

• They are transverse waves
• They require a medium to travel
• They can travel through a vacuum
• They have no amplitude

How does the amplitude of a sound wave relate to its loudness?

• Higher amplitude means lower loudness
• Higher amplitude means higher loudness
• Amplitude has no effect on loudness
• Loudness is only determined by frequency

What is the range of audible frequencies for a healthy human ear?

• 0 Hz to 20,000 Hz
• 20 Hz to 20,000 Hz
• 20 Hz to 20,500 Hz
• 10 Hz to 15,000 Hz
