3B.2 Stationary waves

Question 1

what is a stationaary ways

Answer 1

a wave that has oscillations in a fixed place, with regions of significant oscillations and regions with negative oscillations, which remain at the same relocation all time

Question 2

inorder for a standing wave to occur the waves must be

Answer 2

coherence waves ie have similar amp the same speed and amp and a constant phase relation

Question 3

what are coherence waves

Answer 3

waves that have the same frequency and have a constant phase relationship

Question 4

does energy travel through a standing wave

Answer 4

no

Question 5

what are progressive waves

Answer 5

a wave that transfers energy via oscillation

Question 6

what are nodes

Answer 6

the are reading on a stationary wave where the amp of oscillations are zero

Question 7

what are antinode

Answer 7

they are regions on a stationary wave where the amp of oscillations are maximum

Question 8

how does the harmonic vary the stationary wavelengths

Answer 8

as the number of harmonics increases the length decreases

Question 9

what is the wavelength of the first harmonic

Answer 9

2L

Question 10

what is the wavelength of the second harmonic

Answer 10

L

Question 11

what is the wavelength of the third harmonic

Answer 11

2L/3

Question 12

what is the wavelength of the fourth harmonic

Answer 12

L/2

Question 13

waves that travel on a stretched spring their speed is affected by

Answer 13

tension

Question 14

the equation of the speed of a wave on a string is

Answer 14

the square root of T/mass per unit length

Question 15

how can we find the frequency using the wave equation and the equation of the speed of a wave on a string

Answer 15

see on page 106

Question 16

what is a sonometer

Answer 16

it is an apparatus used to test the frequency relationships of a string under tension, it is usually made from a horizontal wooden sounding box with a metal wire stretched across the top of the wire

Question 17
