4.3 Light and Lenses Review IPC

Which optical instruments produces a magnified, virtual, and inverted image of small objects?

• a pair of binoculars

• a microscope

• a refracting telescope

• a single lens reflex camera

What does a microscope use that magnifies small, nearby objects?

• two convex mirrors

• one mirror and one concave lens

• one mirror and one convex mirror

• three concave lenses

What do reflecting telescopes use that produces a real image, which is then magnified by a convex lens?

• concave lenses

• reflectors

• mirrors

• apertures

IP.6F: construct and communicate an evidence-based explanation for how wave interference, reflection, and refraction are used in technology such as medicine, communication, and scientific research; and

• reflecting telescope

• binoculars

• microscope

• refracting telescope

What type of image does a convex lens form?

• a same-size real image

• a same-size virtual image

• an enlarged-size real image

• an enlarged-size virtual image

Which type of mirror is used in technologies like telescopes and headlights because it reflects light to a focal point?

• Concave
• Plane

• Convex

• Transparent

What is the distance from the center of a mirror to the focal point called?

• reflection length

• divergence length

• refraction length

• focal length

How does the wavelength of the laser light of the player influence the quality of the resulting video?

• The waves would be shorter and more would fit on the disc. This would also be higher quality.

• Low quality and less would fit on disc

• The waves would be longer and fit on the disc better.

• All the Above

Why does white light separate into a rainbow of colors in prisms and water droplets?

• Different wavelengths of light reflect at different angles.

• Some wavelengths of light reflect and others do not.

• Some wavelengths of light refract and others do not.

• Different wavelengths of light refract at different angles.

How does a polarizing filter work?

• It increases the brightness of light by combining multiple light waves.

• It blocks all light except light vibrating in a single plane.

• It changes the color of light by altering its frequency.

• It reflects all incoming light to reduce glare completely.
