Answer 1

@Michele_Laino

Answer 2

what is your ans?

Answer 3

since we have three complete cycles within 4.8 meters, then the wavelength is:
4.8/3=1.6 meters

Answer 4

since we have 3 waves
so divide 4.8 by 3
because one wave is equal to wavelength

Answer 5

lol
sorry i did not see your post @Michele_Laino

Answer 6

no worries :) @rvc

Answer 7

the requested velocity, is:
4.8/6=...meters/seconds

Answer 8

period is T= 6 /3 =...second
frequency f= 1/T =... Hz

Answer 9

if the velocity of our wave is unchanged, then we can apply this formula:
\[\Large \lambda f = v\]
from which we get:
\[\Large \lambda = \frac{v}{f} = \frac{{0.8}}{2} = ...meters\]

Answer 10

this is how i did it, i first took the inverse of the Ferquency.....F=1/T which agve me the period

Answer 11

how did you get 14.5 meters/second

Answer 12

v=traveled space/time interval= 4.8/6=0.8 m/second

Answer 13

period is
T=6/3= 2 seconds

Answer 14

I think taht:
since within 6 seconds we have three complete waves, then the period is:T=6/3= 2 seconds

Answer 15

so the corresponding frequency is:
f=1/T= 1/2=0.5 Hertz

Answer 16

when solving for the very first question wavelength.

Answer 17

i mean second cuz time is given after the wavelength question :(

Answer 18

so do we assume we don't know the time while solving for wavelength

Answer 19

as I wrote before, in the last part of the first question, we have to assume that the speed of our wave is the same as before, namely, it is 0.8 m/second

Answer 20

@rvc do i figure out the amplitude? Please help!!!

Answer 21

@Astrophysics

Answer 22

how do i figure out the amplitude? Please help!!!

Answer 23

the picture is at the top.

Answer 24

you can find the amplitude using \[Amplitude = \frac{ Distance }{ Frequency }\]

Answer 25

They are related.

Answer 26

No, the amplitude here is measured in decibels here. I think you're just confusing it because of the formula/ units but not really sure about what this actually means.

Answer 27

\[\lambda = \frac{ v }{ f }\]

Answer 28

can you quickly guide me what to do Please?!?!?!?!

Answer 29

Slow down, ok so we have so we have 3 complete cycles here, so our wavelength is 4.8/3
