Light and Its Properties

What is the definition of Light?

• Light is defined as electromagnetic radiation that can be perceived by the human eye.

• Light is a form of sound that travels through air.

• Light is a type of mechanical wave that requires a medium to travel.

• Light is a chemical reaction that occurs in the sun.

What is the definition of Refraction?

• Refraction is the bending of light as it passes from one medium to another.

• Refraction is the reflection of light from a surface.

• Refraction is the dispersion of light into its component colors.

• Refraction is the absorption of light by a medium.

Reflection is the (a)   of light, heat, or sound after striking a surface.

• return
• bending
• scattering
• absorption

What is the definition of Transparent?

• Transparent

• Opaque

• Translucent

• Reflective

What is the definition of Translucent?

• Translucent is a term used to describe a material that allows light to pass through, but not enough to see through clearly. It is partially transparent.

• Translucent is a term used to describe a material that completely blocks light from passing through.

• Translucent is a term used to describe a material that allows light to pass through completely, making it fully transparent.

• Translucent is a term used to describe a material that reflects all light, making it opaque.

• Opaque is a term used to describe a material that allows light to pass through, but not enough to see through clearly.

• Opaquwe is a term used to describe a material that completely blocks light from passing through.

• Opaque is a term used to describe a material that allows light to pass through completely, making it fully transparent.

• Opaque is a term used to describe a material that lets no light shine through, shadows form.

What determines the color of light?

• Wavelength

• Frequency

• Amplitude

• Speed

What type of energy is formed when light waves are absorbed?

• Thermal energy

• Electrical energy

• Chemical energy

• Nuclear energy

Match the following phenomena with their descriptions.

• Occurs when light bends as it passes through a medium.

• Diffraction

• Occurs when light spreads as it passes through a narrow opening.

• Shadow

• Occurs when light bounces off a surface.

• Refraction

• Occurs when light cannot pass through an object.

• Reflection
