Light Waves

What are light waves?

• Electromagnetic waves that are visible to the human eye.

• Waves that can only be seen with special equipment.

• Sound waves that travel through air.

• Waves that are invisible to the human eye.

What is the visible spectrum?

• The range of wavelengths that can be detected by the human eye, from violet to red.

• The range of wavelengths used in radio communication.

• The range of wavelengths that includes ultraviolet and infrared light.

• The range of wavelengths that can be seen by animals but not humans.

What is reflection of light?

• Reflection of light is the bending of light waves as they pass through different mediums.

• Reflection of light is the bouncing back of light waves when they hit a surface.

• Reflection of light is the absorption of light waves by a surface.

• Reflection of light is the scattering of light waves in different directions.

What is absorption of light?

• The process by which light waves are taken in by a material, converting the light energy into other forms of energy.

• The reflection of light waves off a surface without any energy conversion.

• The scattering of light waves in different directions by particles in a medium.

• The transmission of light waves through a material without any interaction.

Which color of light has the longest wavelength in the visible spectrum?

• Blue light

• Green light

• Red light

• Yellow light

What determines the color of visible light?

• The intensity of the light

• The wavelength of the light

• The speed of the light

• The frequency of the light

What is the speed of light?

• 299,792 kilometers per second (km/s)

• 150,000 kilometers per second (km/s)

• 300,000 kilometers per second (km/s)

• 1,000,000 kilometers per second (km/s)

What is transmission of light?

• Transmission of light is the process by which light passes through a medium without being absorbed.

• Transmission of light is the reflection of light off a surface.

• Transmission of light is the scattering of light in different directions.

• Transmission of light is the absorption of light by a medium.

What is a prism?

• A solid object that reflects light without changing its color.

• A transparent optical element that refracts light, separating it into its constituent colors.

• A type of lens used to magnify objects.

• A device that absorbs light and converts it into heat.

Which color of light has the highest energy in the visible spectrum?

• Red light

• Green light

• Violet light

• Blue light
