how do you know which equation to use if your calculating waves? do you use F=wave or T=seconds ? seconds wave
@aminanaiga33447 ай бұрын
Depends on which one they gave u in the question or the easiest one for you can still get the same answer
@disemelokwaikwai24806 ай бұрын
Sir can i ask? Will it be wrong if i used th formula V=d/t to find the speed of the wave.
@user-zf3rl3fe4q6 ай бұрын
According to my understanding, V=d/t applies to situations we're we know the distance, if not we use the other one.

what is the answer for the wave calculation in the video @ 18:31
@thandore5 ай бұрын
Wait so does the 1 in f=1/T change depending on how many cycles there are?
@Lethzie5 ай бұрын
No it's constant because frequency is the number of waves that move past a fixed point per 1 second
@sewelalesedi51933 ай бұрын
Frequency is the number of waves that pass a fixed point per second the 1 will change depending on the number of waves (1 represents the no of waves ) so if there were 2 waves that pass in one second it would be 2/T ( the T represents the time it takes for one complete wavelength to pass a given point measured in seconds)

Hello sir, what does 'in phase' mean
@PraiseMai7 ай бұрын
I think he means, like particles that are moving the same way ,like in the picture between the two points they both moving up and down
@SheCondy-ee2uf7 ай бұрын
It means that two waves or pulses are in the same rest position or equilibrium
@SheCondy-ee2uf7 ай бұрын
For you to always remember know that in Phase is constructive interference and out of phase is destructive interference
@aminanaiga33447 ай бұрын
It is when two points of a wave are going in the same direction

phase is another word for state in this case
