Interaction of Light

What are the three types of materials based on their ability to transmit light?

• conductor, insulator, semiconductor

• metallic, non-metallic, metalloid

• transparent, translucent, and opaque

• solid, liquid, gas

Explain the difference between transparent and translucent materials.

• Transparent materials block all light from passing through, while translucent materials allow light to pass through clearly.

• Transparent materials are solid, while translucent materials are liquid.

• Transparent materials allow light to pass through clearly, while translucent materials allow some light to pass through but may cause objects to appear blurry or distorted.

• Transparent materials absorb light completely, while translucent materials reflect light partially.

How is a mirror an example of regular reflection?

• The mirror reflects light at a different angle than the incident angle, which is characteristic of regular reflection.

• A mirror does not reflect light, so it is not an example of regular reflection.

• Regular reflection only occurs in water, not in mirrors.

• The mirror reflects light at the same angle as the incident angle, which is characteristic of regular reflection.

What are the primary colors of light?

• Red, Green, Blue

• Cyan, Magenta, Yellow

• Red, Orange, Purple

• Yellow, Green, Blue

What happens when all the primary colors of light are combined?

• No light is created.

• Black light is created.

• White light is created.

• Rainbow light is created.

What is the difference between reflection and refraction?

• Reflection is the bouncing back of light, while refraction is the bending of light.

• Reflection is the bending of light, while refraction is the bouncing back of light.

• Reflection is the absorption of light, while refraction is the emission of light.

• Reflection is the slowing down of light, while refraction is the speeding up of light.

Explain how a rainbow is formed.

• Rainbows are created by giant mirrors in the sky reflecting light

• Rainbows are formed by unicorns spraying water from their horns

• Rainbows are the result of aliens using advanced technology to project colors in the atmosphere

• Sunlight is refracted, reflected, and dispersed in water droplets in the atmosphere, creating a spectrum of light in the form of a multicolored arc.

What is the difference between opaque and translucent materials?

• The difference between opaque and translucent materials is that opaque materials allow light to pass through, while translucent materials do not allow light to pass through.

• The difference between opaque and translucent materials is that opaque materials do not allow light to pass through, while translucent materials allow some light to pass through but not enough to clearly see through.

• Opaque materials allow some light to pass through but not enough to clearly see through, while translucent materials do not allow any light to pass through.

• The difference between opaque and translucent materials is that opaque materials allow clear visibility through them, while translucent materials do not allow any visibility.

How does the color of an object change when it is viewed under different colors of light?

• The color of an object does not change under different colors of light

• The color of an object changes due to the temperature of the light

• The color of an object changes due to the humidity of the light

• The color of an object changes when it is viewed under different colors of light due to the reflection or absorption of different wavelengths of light.
