the diagram shows a clear plastic lens. a lens convex on the left and concave on the right. a student shines a flashlight on the lens. which best describes what happens when light rays exit the lens? they are all refracted away from a central axis. they are all refracted toward a central axis. they exit parallel to the path in which they entered. they exit at a slower speed from which they entered.

The flashlight's beam will all be refracted towards a central axis. But, this is still dependent on the type of lens that is used for the said activity. The speed of light will vary depending whether the lens is a concave or a convex lens. The exit point of the light will always head towards the central axis.

They will all be refracted toward a central axis

Explanation:

They are going to bend the light in toward a central axis because they will either magnify, or deacrease the sizes. On a concave there will eventually be a focal point and the image will flip.

we need to know the time interval during which the force acts. impulse of force = momentum change
