Light, Shadow, and Reflection

What is light?

• Light is a type of gas.

• Light is electromagnetic radiation that is visible to the human eye.

• Light is a type of solid matter.

• Light is a form of sound waves.

How are shadows formed?

• Shadows are formed by dancing unicorns

• Shadows are formed when an object blocks light.

• Shadows are formed by magical spells

• Shadows are formed by invisible fairies

What is reflection of light?

• Reflection of light is the process where light travels through a surface without any change.

• Reflection of light is the process where light changes color when it hits a surface.

• Reflection of light is the process where light bounces off a surface, changing direction but not its wavelength.

• Reflection of light is the process where light is absorbed by a surface and disappears.

Explain the difference between transparent, translucent, and opaque objects.

• Transparent objects absorb light completely, translucent objects allow light to pass through completely, and opaque objects allow some light to pass through but not completely.

• Transparent objects reflect light completely, translucent objects allow some light to pass through but not completely, and opaque objects absorb light completely.

• Transparent objects allow light to pass through completely, translucent objects do not allow light to pass through at all, and opaque objects allow some light to pass through but not completely.

• Transparent objects allow light to pass through completely, translucent objects allow some light to pass through but not completely, and opaque objects do not allow light to pass through at all.

Why do we see our reflection in a mirror?

• Light bounces off the mirror's surface and back to our eyes.

• Reflections are a natural phenomenon

• Our thoughts are projected onto the mirror

• Mirrors emit light that creates our reflection

What is the law of reflection?

• Angle of incidence = Angle of reflection

• Reflection only occurs in transparent materials

• Angle of incidence = 90 degrees

• Angle of reflection = Angle of refraction

How does a concave mirror differ from a convex mirror?

• A concave mirror diverges light, while a convex mirror focuses light.

• A concave mirror reflects light, while a convex mirror absorbs light.

• A concave mirror enlarges images, while a convex mirror shrinks images.

• A concave mirror focuses light, while a convex mirror diverges light.

What is the role of a pinhole camera in understanding light?

• To block light from entering the camera

• To demonstrate how light travels in straight lines and how an image is formed through a small opening without the need for a lens.

• To create colorful light patterns

• To capture high-resolution images

Describe the phenomenon of refraction of light.

• Refraction of light is caused by the reflection of light off surfaces.

• The phenomenon of refraction of light involves the bending of light as it passes from one medium to another due to the change in its speed.

• Refraction of light occurs due to the absorption of light by the medium.

• Refraction of light is a result of light traveling at a constant speed in all mediums.

How does a prism separate white light into its constituent colors?

• Reflection at different angles based on wavelength

• Absorption of different colors based on wavelength

• Refraction at different angles based on wavelength

• Diffraction at different angles based on wavelength
