CL.5 BK.2-1-Properties of Light

What do we need to see things?

• Color

• Light

• Sound

• Darkness

How does light travel?

• Light travels as particles only and does not have a speed.

• Light travels in waves at a speed of approximately 299,792 kilometers per second.

• Light travels in straight lines at a speed of 300,000 kilometers per second.

• Light travels in circles at a speed of 150,000 kilometers per second.

Can light pass through glass?

• Glass blocks all forms of light.

• Yes, light can pass through glass.

• Light can only pass through colored glass.

• No, light cannot pass through glass.

What happens when light hits an opaque object?

• Light creates a shadow behind the opaque object without any interaction.

• Light is either absorbed or reflected by the opaque object.

• Light passes through the opaque object completely.

• Light is transformed into sound when it hits the opaque object.

What is formed when light is blocked?

• Brightness

• Reflection

• Illumination

• Shadow

How does a smooth surface like a mirror affect light?

• A smooth surface like a mirror absorbs all light, preventing any reflection.

• A smooth surface like a mirror scatters light in all directions, creating a blurry image.

• A smooth surface like a mirror reflects light uniformly, creating clear images.

• A smooth surface like a mirror bends light, causing it to change color.

What is the size of an image in a plane mirror compared to the object?

• The size of the image is the same as the size of the object.

• The size of the image is smaller than the size of the object.

• The size of the image varies depending on the distance from the mirror.

• The size of the image is larger than the size of the object.

What does it mean when an image is laterally inverted?

• An image is laterally inverted when it is flipped vertically, making the top appear on the bottom and vice versa.

• An image is laterally inverted when it is flipped horizontally, making the left side appear on the right and vice versa.

• An image is laterally inverted when it is rotated 90 degrees, changing its orientation completely.

• An image is laterally inverted when it is blurred, causing a loss of detail and clarity.

How does the size of an image in a convex mirror compare to the object?

• The image in a convex mirror is inverted compared to the object.

• The image in a convex mirror is smaller than the object.

• The image in a convex mirror is larger than the object.

• The image in a convex mirror is the same size as the object.

What advantage does a convex mirror provide?

• Enhanced night vision.

• Narrower field of view.

• Wider field of view.

• Increased image distortion.
