Light and Waves Quiz

What happens when light bounces off a surface?

• Refraction

• Reflection

• Dispersion

• Diffusion

What do we call the light that hits a mirror?

• Reflected ray

• Refracted ray

• Incident ray

• Normal ray

The angle of incidence is always equal to the:

• Critical angle

• Angle of dispersion

• Angle of reflection

• Refraction index

Refraction is the:

• Bending of sound

• Reflection of light

• Bending of light

• Transmission of waves

What is the speed of light in a vacuum?

• 300,000 m/s

• 3x10⁶ m/s

• 3x10⁸ m/s

• 3x10⁵ km/h

The index of refraction compares:

• Angle of incidence to angle of reflection

• The speed of light in different media

• Length and wavelength

• Light and sound waves

What causes dispersion?

• Mirror reflection

• White light passing through a prism

• Bending of sound waves

• Magnetic field interaction

Who first demonstrated light dispersion using a prism?

• Einstein

• Young

• Newton

• Galileo

What is polarization?

• Bending of light in water

• Limiting oscillations of light to one plane

• Separating light into colors

• Filtering light completely

What is unpolarized light?

• Light with only vertical oscillations

• Light traveling in circles

• Light oscillating in all directions

• Filtered light
