Light and Space Quiz

What is light reflection?

• Light reflection is the process by which light bounces off a surface.

• Light reflection is the emission of light from a surface.

• Light reflection is the bending of light around an object.

• Light reflection is the absorption of light by a surface.

Explain the concept of light refraction.

• Light refraction is the reflection of light off a surface

• Light refraction is the splitting of light into its component colors

• Light refraction is the absorption of light by a medium

• Light refraction is the bending of light as it passes from one medium to another due to a change in its speed.

How are rainbows formed?

• Rainbows are a result of aliens using advanced technology to project light in the atmosphere.

• Sunlight is refracted, reflected, and dispersed in water droplets in the atmosphere.

• Rainbows are formed by moonlight reflecting off water droplets.

• Rainbows are created by unicorns painting the sky with colors.

What are galaxies in space?

• Galaxies are individual planets in the universe.

• Galaxies are small clusters of stars within a solar system.

• Galaxies are massive systems of stars, stellar remnants, interstellar gas, dust, dark matter, and other astronomical objects bound together by gravity.

• Galaxies are fictional creations in science fiction movies.

Differentiate between asteroids and meteoroids.

• Asteroids are made of ice, while meteoroids are made of rock.

• Asteroids are larger rocky bodies found in the asteroid belt, while meteoroids are smaller rocky or metallic bodies that become meteors when entering Earth's atmosphere.

• Asteroids are only found on Earth, while meteoroids are found in space.

• Asteroids are always smaller than meteoroids.

Describe the composition of comets.

• Comets are composed of ice, dust, rocky material, and organic compounds.

• Comets are made entirely of metal.

• Comets consist of liquid water and rocks.

• Comets are composed of gas only.

What happens during light reflection?

• Light waves bounce off a surface at the same angle they hit it.

• Light waves are absorbed by the surface

• Light waves change color during reflection

• Light waves travel through the surface

Give an example of light refraction in daily life.

• A pencil appearing broken when placed in a glass of water.

• A mirror reflecting light at an angle.

• A book appearing larger when viewed through a magnifying glass.

• A straw appearing bent when placed in a glass of water.

Why do rainbows appear after rain?

• Rainbows appear due to a secret government weather control program

• Sunlight is refracted, reflected, and dispersed in water droplets in the atmosphere, creating a spectrum of light that we perceive as a rainbow.

• Rainbows are a result of aliens experimenting with light manipulation

• Rainbows are caused by unicorns dancing in the sky

How are galaxies classified?

• Based on shape, size, and characteristics

• Based on color, temperature, and distance

• According to their location in the universe

• By their age, composition, and brightness
