Pre-Test LENSES AND REFRACTIVE INDEX (L0)

If light rays come from a less dense medium to a denser medium, the rays will be refracted towards the normal line, and vice versa. The following statement is from the Law of...

• Newton

• Ohm

• Snellius

• Hooke

One of the benefits of measuring the refractive index is

• to measure the purity of a substance or compound

• to measure the length of an object

• to measure the speed of a vehicle

• to measure the volume of a solution

A transparent object bounded by two refractive surfaces with at least one curved surface is called

• Lamp

• Lens

• Screen

• Mirror

The purpose of the lens and refractive index practicum, except for

• Determining the transparency level of glass

• Determining the refractive index of materials

• Understanding the properties and determining the strength and magnification of lenses

• Understanding Snell's law

One of the data and units measured in the refractive index experiment is:

• Focal length of the lens and meters

• Distance and meters

• Angle of refraction and degrees

• Lens strength and diopters

The tool used to measure the distance of the image is:

• Caliper

• Multimeter

• Ruler

• Micrometer screw

The type of lens used in the L0 practicum is:

• Converging lens

• Double concave lens

• Mirror

• Diverging lens

• Angle of Refraction

• Magnification of the Lens

• Focal Length of the Lens

• Angle of Incidence

In the diagram below, the item on the far left is:

• Antenna

• Mirror

• Object

• Screen

The tool used to measure the angle of refraction is:

• Ruler

• Caliper

• Compass

• Protractor
