Light Exploration

An image that cannot be obtained on a screen is called a ____________.

• real

• virtual

• transparent

• opaque

Explain the difference between reflection and refraction of light.

• Reflection and refraction both involve light bending in the same direction.

• Reflection occurs when light passes through a medium, while refraction involves changing speed.

• Reflection of light involves bouncing off a surface, following the law of reflection. Refraction of light occurs when light passes through a medium and changes speed, causing it to bend.

• Reflection is the bending of light, while refraction is the bouncing off a surface.

How does light interact with a concave mirror?

• when light rays strike its reflecting surface, they diverge or spread out

• when light rays strike and reflect from its reflecting surface, they converge or come together at a specific point known as the focal point.

• Light rays diverge at the focal point in front of the mirror

• Light rays passing through the focal point reflect back towards the light source

What causes the formation of a rainbow?

• Moonlight being refracted, reflected, and dispersed in water droplets in the atmosphere

• Raindrops being absorbed by the sunlight and creating a spectrum of colors

• Clouds colliding and producing a colorful arc in the sky

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

Describe the uses of convex lens.

• Convex lenses are used in magnifying glasses, cameras, projectors, and corrective lenses for vision.

• Convex lenses are used in telescopes

• Convex lenses are used in binoculars

• Convex lenses are used in microscopes

In which direction does light bend when passing through a convex lens?

• Parallel to the normal line

• Towards the normal line

• Away from the normal line

• Does not bend

How does a concave mirror reflect light?

• Diverging light rays away from a focal point

• Absorbing light without reflection

• Reflecting light in a straight line

• Converging light rays towards a focal point

What are some examples of natural sources of light?

• moon

• sun, stars, fireflies, lightning

• candles

• lava

What happens when light passes through a concave lens?

• Light diverges or spreads out

• Light passes straight through

• Light reflects off the lens

• Light converges
