Kinsey is having a challenging time reading the board at school. Her optometrist, or eye doctor, suggests that she get glasses. What is the best reason glasses would help Kinsey read?

Glasses are reflective and cause light to bounce away from her eyes, which makes it easier to see the board.

Glasses are reflective and cause light to bounce into her eyes faster.

Glasses are refractive and cause light to bend, which can make objects seem more clear.

Glasses are refractive can cause light to scatter, which can make objects appear brighter.

Quinn can see through the cup with water because it is opaque, but milk is transparent.

Quinn can see through the cup with milk because it is opaque, but water is transparent.

Quinn can see through the cup with water because it is transparent, but milk is opaque.

Quinn can see through the cup with water because it is translucent, but milk is transparent.

Maya builds a device that uses a flashlight and a reflective surface, like a mirror, to point the beam of light in different directions. The picture shows her device. How would the light be impacted if Maya changed the mirror to a prism?

light would still bounce off of the prism back in the direction of the light

light would be absorbed in the prism and no light would shine through

light would be bent as it passes through a prism in different directions

light would be curved in a circular motion and moves back toward the source

Jonathan notices his dad hung two objects in their window at home. When he walks by the window one day, he sees that light reacts differently when it hits both objects. When light hits object A, he can see a rainbow on the ground. When light hits object B, none of the light passes through. What is true of each object?

Object A is an opaque object and object B is a prism.

Object A is a prism and object B is translucent.

Object A is a translucent object and object B is an opaque object.

Object A is a prism and object B is an opaque object.
