Pre Unit 3A: Property of Light, EMS, Fission, Fusion of the Sun

What causes rainbows to occur?

• Sunlight passing through water droplets causing refraction or bending of light

• Sunlight reflecting off water droplets

• Sunlight being absorbed by water droplets

• Sunlight passing through clouds

Why can't you observe a rainbow during the rain storm?

• Rainbows are a myth and do not actually exist.
• Rain clouds are thick and dark making impossible for sunlight to pass the raindrops as they fall.

• Rainbows can only be seen during sunny weather.
• Rainbows can only be seen at night.

What factors cause the rainbow phenomena?

• Reflection, refraction, and dispersion of light in water droplets
• Absorption and emission of light by water droplets
• Reflection, refraction, and dispersion of light in air
• Interference of light waves in the atmosphere

Why do we see distinct bands of colors in a rainbow?

• Because each color of the rainbow has a different wavelength and is refracted at a slightly different angle

• Because the sunlight is reflected off water droplets in the air

• Because rainbows are formed by unicorns

• Because the colors of the rainbow are created by magic

What is the relationship between wavelength and rainbow?

• Rainbows are formed by the interaction of sound waves.
• Different wavelengths of light are refracted and dispersed by water droplets in the atmosphere, creating the colors of the rainbow.
• Rainbows are caused by the reflection of light off of a surface.
• Rainbows are created by the absorption of light by water droplets.

What is nuclear fission?

• A process that involves splitting the nucleus of an atom

• A process that involves combining the nucleus of an atom

• A process that involves releasing energy from the nucleus of an atom

• A process that involves converting the nucleus of an atom into a different element
