BMST Waves, Sound, and Light 3

Question 1

What is a transverse wave?

Accepted Answer

A wave where particles move perpendicular to the wave direction

Answer

A wave where particles move parallel to the wave direction

Answer

A wave that requires no medium to travel

Answer

A wave that only travels through solids

Question 2

Which formula correctly calculates wave speed?

Accepted Answer

v = f × λ

Answer

v = f / λ

Answer

v = λ / f

Answer

v = f + λ

Question 3

What occurs when two waves meet and their displacements combine to produce a larger amplitude wave?

Accepted Answer

Constructive interference

Answer

Destructive interference

Answer

Diffraction

Answer

Refraction

Question 4

What does the index of refraction of a material measure?

Accepted Answer

The ratio of the speed of light in vacuum to the speed of light in that material

Answer

The angle at which light reflects off the material's surface

Answer

The percentage of light absorbed by the material

Answer

The frequency of light as it travels through the material

Question 5

What is resonance in the context of waves and vibrating systems?

Accepted Answer

The tendency of a system to oscillate with greater amplitude at certain natural frequencies

Answer

The splitting of a wave into two separate waves

Answer

The blocking of wave energy by a dense barrier

Answer

The conversion of sound wave energy into thermal energy

Question 6

Which statement correctly describes a longitudinal wave?

Accepted Answer

Particles vibrate parallel to the direction of wave travel

Answer

Particles vibrate at right angles to the direction of wave travel

Answer

The wave can only travel through electromagnetic fields

Answer

The wave always has visible crests and troughs

Question 7

What happens to the wavelength of light when it enters a medium with a higher index of refraction?

Accepted Answer

It decreases

Answer

It increases

Answer

It remains the same

Answer

It doubles
