Applications of Lenses

What is an example of an application of convex lenses?

• Binoculars

• Microscopes

• Magnifying glasses or reading glasses

• Telescopes

Name one application of concave lenses.

• Musical instruments

• Correcting visual impairments

• Automotive parts

• Cooking utensils

How do camera lenses work in capturing images?

• Camera lenses capture images by absorbing light onto a photosensitive surface.

• Camera lenses capture images by focusing light onto a photosensitive surface.

• Camera lenses capture images by reflecting light onto a photosensitive surface.

• Camera lenses capture images by dispersing light onto a photosensitive surface.

What is the purpose of eyeglasses in correcting vision?

• Eyeglasses correct vision by changing the color of objects seen.

• Eyeglasses correct vision by enhancing peripheral vision.

• Eyeglasses correct vision by bending light rays to focus properly on the retina.

• Eyeglasses correct vision by emitting a special frequency of light.

Explain how microscopes use lenses to magnify small objects.

• Microscopes use lenses to bend light rays and magnify small objects.

• Microscopes use lenses to reflect light rays and magnify small objects.

• Microscopes use lenses to absorb light rays and magnify small objects.

• Microscopes use lenses to disperse light rays and magnify small objects.

How are convex lenses used in magnifying glasses?

• Convex lenses are used in magnifying glasses to block light rays and reduce image size.

• Convex lenses are used in magnifying glasses to scatter light rays and distort the image.

• Convex lenses are used in magnifying glasses to converge light rays and create a magnified image.

• Convex lenses are used in magnifying glasses to diverge light rays and create a smaller image.

Describe the role of concave lenses in correcting nearsightedness.

• Concave lenses correct nearsightedness by diverging light rays before they reach the eye, allowing the image to be properly focused on the retina.

• Concave lenses correct nearsightedness by converging light rays before they reach the eye.

• Concave lenses correct nearsightedness by reflecting light rays before they reach the eye.

• Concave lenses correct nearsightedness by absorbing light rays before they reach the eye.

What type of lenses are used in binoculars for viewing distant objects?

• Convex lenses

• Plano-convex lenses

• Concave lenses

• Fisheye lenses

In what way do lenses contribute to the functioning of projectors?

• Lenses absorb light and reduce brightness.

• Lenses create sound effects in projectors.

• Lenses increase the weight of projectors.

• Lenses focus and direct light onto the screen.
