Please help if i fail this test im gonna fail:(( 1.Black is the absence of all light. So why do the fur and pupils of this cat appear to us to be black?

A
The fur and pupils of the cat only reflect the black wavelength of light back to our eyes.

B
There is no light in the room where the cat is located.

C
The fur and pupils of the cat absorb all of the light waves so our eyes detect black.

D
The fur and pupils of the cat reflect all light waves back to our eyes.

D
An X-ray wave has a higher frequency than an infrared wave.

Which statement best describes diffraction?

A
Light energy is absorbed by surrounding matter.

B
Light slows down as it passes through a medium.

C
Light bounces off a medium.

D
Light bends around an object.

The visible light spectrum from its longest to shortest wavelength is...

A
Infrared, red, orange, yellow, green, blue, indigo, violet, ultraviolet.

B
Red, orange, yellow, green, blue, indigo, violet.

C
Ultraviolet, violet, indigo, blue, green, yellow, orange, red, infrared.

Which of the following statements about how light waves travel is correct?

A
Light waves travel faster through solids than through air.

B
Light waves travel the fastest through liquids and slowest through the air.

C
Light waves travel faster through the air than through solids.

D
Light waves travel the fastest through solids and slowest through liquids.

A model of a concave lens is shown in the diagram. Which of the following describes a possible application of this type of lens?

A
Concave lenses can be used in laser pointers to converge the projected light to a single point.

B
Concave lenses can be used in mirrors to make objects appear closer than they truly are.

C
Concave lenses can be used in car headlights to spread the projected light outwards.

D
Concave lenses can be used in microscopes to make small objects appear larger.

Mrs. Lewis places a stick in a pond. When she looked down at the stick, it appeared to be broken at the point where the stick entered the water. This was caused by:

A
absorption of light waves by the stick.

B
refraction of light waves passing from air into water.

C
diffraction of light waves around the stick.

D
reflection of light from the water.
