WorksheetsCHAPTER 3: LESSON 1 - LIGHT
Total questions: 15
Worksheet time: 12mins
What are the properties of light?
Reflection, refraction, dispersion
Absorption, emission, and transmission
Speed, mass, and charge
Color, temperature, and density
What is the difference between reflection and refraction?
Reflection is the absorption of light; refraction is the scattering of light.
Reflection involves bouncing back of light; refraction involves bending of light.
Reflection and refraction both involve the same process of light passing through materials.
Reflection occurs only in water; refraction occurs only in air.
How do prisms separate light into colors?
Prisms create colors by emitting light from their surfaces.
Prisms separate light by absorbing certain colors and reflecting others.
Prisms separate light into colors by refracting it, bending different wavelengths by varying amounts.
Prisms separate light by generating heat that changes its color.
What is the relationship between energy and wavelength?
Energy and wavelength are inversely proportional
Energy and wavelength are directly proportional
Increasing energy results in longer wavelength.
Wavelength has no effect on energy.
What happens to light when it passes from air to water?
Light disappears completely when it enters the water.
Light reflects off the surface and does not enter the water.
Light speeds up and changes color when it passes from air to water.
Light bends and slows down when it passes from air to water.
How do we perceive different colors of light?
We perceive colors through the vibration of air molecules.
Different colors are seen based on the temperature of the light source.
We perceive different colors of light through the stimulation of cone cells in the retina that respond to specific wavelengths.
Colors are perceived by the brain interpreting sound waves.
What is the electromagnetic spectrum?
The electromagnetic spectrum is a type of sound wave.
The electromagnetic spectrum only includes visible light.
The electromagnetic spectrum is a measure of temperature variations.
The electromagnetic spectrum is the range of all electromagnetic radiation types, categorized by wavelength and frequency.
Which property of light enables the formation of a rainbow?
I. color separation
II. dispersion
III. reflection
IV. refraction
I and III
II, III and IV
I, III, and IV
I, II, III and IV

In this picture, the pencil appears broken. As light waves move from one material into another, they bend and change direction. This is called...
refraction
spreading
reflection
scattering
When light hits an object, it is sometimes absorbed by that object. What is the process that describes when light bounces off an object?
refraction
reflection
rotation
diffraction
