Physics Girl: Spoon Reflection Riddle

What happens to your reflection when you look at the scoop side of a spoon?

• It becomes blurry.

• It appears upside down.

• It appears right side up.

• It disappears completely.

What is the effect of moving a spoon closer to your eye?

• The reflection becomes inverted.

• The reflection becomes right side up.

• The reflection disappears.

• The reflection becomes distorted.

What type of image is formed when light rays actually meet at a point?

• Real image

• Virtual image

• Distorted image

• Inverted image

What is a virtual image?

• An image that is always right side up

• An image that appears to be in a location where light does not actually reach

• An image formed by converging light rays

• An image that can be projected on a screen

At what point do light rays become parallel and no image is formed?

• At the center of curvature

• At the edge of the mirror

• At the vertex

• At the focal point

What happens to the image as you move closer to a concave mirror?

• It gets smaller and remains inverted.

• It gets larger and remains inverted.

• It gets larger and flips right side up.

• It disappears completely.

What happens to the image when a concave mirror is curved outward?

• It becomes blurry and then flips.

• It disappears completely.

• It becomes larger and right side up.

• It becomes smaller and inverted.

What is the significance of the focal point in a concave mirror?

• It is where the image is always formed.

• It is where light rays converge or appear to converge.

• It is the point where the mirror is the thickest.

• It is the point where the mirror is the thinnest.

What is the purpose of adaptive optics in telescopes?

• To change the color of images

• To reverse atmospheric distortion

• To magnify distant objects

• To increase the field of view

How do deformable interocular lenses benefit the eye?

• They increase the size of the pupil.

• They reduce eye strain.

• They allow focusing at different distances.

• They change the eye color.
