Mounted Component Resistor 1Kohm

Allows students to conduct experiments to measure the speed of light. Reflect a laser off a movable mirror into a light receiver to measure phase differences.

Allows the students observation of velocity of drop rising in an electric field, then permits calculation of the force on the charge carried by the oil drop.

Set of four 4 oz bottles of mineral oil, for use with the Millikan Oil Drop Apparatus.
