Physics Quiz

Question 1

Crest (Property of Transverse Waves)

Answer 1

The highest point on the wave

Question 2

Trough (Property of Transverse Waves)

Answer 2

The lowest point on the wave

Question 3

Wavelength (Property of Transverse Waves)

Answer 3

The distance from crest to crest or from trough to trough

Question 4

Amplitude (Property of Transverse Waves)

Answer 4

The height of the wave from the rest position to the crest, or from the rest position to the trough

Question 5

Rest position - Equilibrium (Property of Transverse Waves)

Answer 5

The place where there is no wave

Question 6

Light

Answer 6

Form of radiant energy

Question 7

Frequency

Answer 7

The rate of repetition of a wave

Higher = more energy the wave passes along

Question 8

Example of Frequency

Answer 8

What is the speed, if the wavelength is 10cm and the frequency is 5 cycles/sec?

5 cycles/sec x 10cm = 50cm/sec

Question 9

Electromagnetic radiation

Answer 9

A wave pattern made of electric and magnetic fields that can travel through empty space.

-ranges from gamma rays (shortest) to radio waves (longest), called the electromagnetic spectrum

Question 10

Luminous vs. Non luminous

Answer 10

Luminous: an object that gives off its own light (lightbulb, sun)

Non luminous: an object that does not produce its own light (tree, moon)

Question 11

Incandescence

Answer 11

Light that is produced by an object that is at a very high temp (sun, lightbulb, fire)

Question 12

Properties of light

Answer 12

1. Transmitted
2. Reflected
3. Absorbed

Question 13

Transparent

Answer 13

Clear

Question 14

Translucent

Answer 14

Somewhat see-through

Question 15

Opaque

Answer 15

Cannot see through; mirror

Question 16

Shadows

Answer 16

Forms when an opaque object blocks light rays from a light source
