Waves in One Dimension

Question 1

Waves are ______ carriers.

Answer 1

energy

Question 2

What are the two general classes of waves?

Answer 2

1. Electromagnetic
2. Mechanical

Question 3

Electromagnetic or light waves are capable of moving through what?

Answer 3

objects or the vacuum of space

Question 4

Mechanical waves require a ______ of some kind through which they can travel

Answer 4

medium

Question 5

What are the two types of classes of mechanical waves?

Answer 5

1. Transverse
2. Longitudinal

Question 6

For a transverse wave the particles in the medium vibrate _____________ to the direction of motion of the wave energy

Answer 6

perpendicular

Question 7

Longitudinal waves are also called what?

Answer 7

Compression and Pressure waves

Question 8

Longitudinal waves are also called what?

Answer 8

Compression and Pressure waves

Question 9

For longitudinal waves the particles in the medium vibrate ________ to the direction of motion of the wave energy.

Answer 9

parallel

Question 10

Longitudinal waves travel by causing what in the medium?

Answer 10

instantaneous compressions and rarefactions

Question 11

A wave _____ is a disturbance that has a beginning and an end

Answer 11

pulse

Question 12

The amplitude of a wave pulse or a wave is the maximum displacement of the medium from the ___________ position.

Answer 12

equilibrium

Question 13

For any type or class of wave, the wavelength of a wave is equal to the distance between two points which are in the exact same _____ or position on the wave.

Answer 13

phase

Question 14

(T) the time it takes for the wave to travel one wavelength of distance

Answer 14

period

Question 15

(F) the number of pulses or vibrations of wavelengths which occur in one second

Answer 15

Frequency

Question 16

what are the 3 things that DO NOT depend on the amplitude of the wave?

Answer 16

Wavelength, Period, and Frequency

Question 17

(JUST STARE AT THE EQUATION AND REMEMBER) For all waves, there is a simple relation between speed, frequency and wavelength.

Answer 17

V = λ/T –> λ/(1/F) –> λF

Question 18

When a wave or a pulse on a string or rope meets a boundary of some kind, some or all of the wave energy will be _________ by the boundary.

Answer 18

reflected

Question 19

If the boundary is a FIXED end, the reflected pulse will be ________ relative to the incident pulse

Answer 19

Inverted

Question 20

If the boundary involves a free end, the reflected pulse will be ________ relative to the incident pulse

Answer 20

upright
