The student is observing part of a plant with a microscope. Which statement describes a behavior of light in the microscope?

• Light travels through the microscope without changing

• moving in straight lines causes light to increase in brightness

• Light refracts through the lens of the microscope

• moving in straight lines keeps light from reflecting

For a class demonstration a student turned off the lights in the classroom. The student then shined light from a flashlight through a hole in a piece of cardboard. The class saw the narrow beam of light continue until another student placed a mirror in the lights path. The light did not continue past the mirror because--

• light can not travel very far

• the mirror absorbed all the light

• the light was refracted back to the light source

• light travels in straight line and cannot go around objects

A student conducts an investigation by shinning a flashlight toward a flat mirror. The the student changes the angle of the mirror and observes the path of the reflected light. As the mirror changes direction the light reaching the mirror can reach the ceiling because the light--

• travels in straight lines and reflects from the surface of the mirror

• refracts in the glass of the mirror and is spread out over the room

• enters the mirror and changes direction when it is refracted by the back of the mirror

• travels through air and does not change its direction in air

Students conduct experiments to investigate friction. Which experiment will best test the effect of friction on objects?

• drop two balls from the same height at the same time

• roll two marbles on the carpet from the same starting point at the same time and with the same of force

• role three marbles across three different surfaces from the same starting point and with the same amount of force

• release two balls from the top of a ramp at the same time
