I must be really dumb or smth bc I’m still not understanding. It’s ok tho dont worry about it

i dont quite understand what this means

So what youre saying is in parallel both components have the same potential for charge carriers to do work so theyre the same?

Hi is there a specific timestamp for my question?

As the title says, i am struggling to understand how if the cell is only supplying 3V how 2 lamps in parallel both receive 3 volts (totalling 6) I currently study a level physics and never really questioned how this works and just accepted it as the truth. Can someone explain with a helpful...

When 2 or more microwaves come togetehr at the receiver they superpose and the resultant wave displacement is the sum of the individual waves displacements. Maxima exist when the waves are even pi radians out of phase and therefore the max displacements of the incident waves add up to create a...

Yes I understand how you only require one as long as you know the order. Thanks for helpjng

i believe it is one wavelength due to the fact that the distance between adjacent maxima are one wavelength apart. Ive realsied ive only done from the transmitter to the reflector which is only half the distance so that is why i am off by a factor of two

i thought because it converges back to a singular point it doesnt matter, i see my mistake now thank you. How would you answer the non-calculation part of the question?

im sorry but i do not understand what you mean. Adjacent maxima are 1 full wavelength apart and that is what i have calculated

The answer is 2.8 not 1.4, how does the wave getting knocked out of phase by 180 degrees mean my calculation for wavelength is off by a factor of 2?

The answer is 2.8 which is double the value I calculated for wavelength. How does the fact it gets knocked 180 degrees out of phase cause my calculation or be off by a factor of 2?

I hate to revive this thread after seeing the tragedy before. I’m also stuck on this question and read through this thread a million times to try to understand the answer. How does the reflection knocking the reflected waves another 1/2 lambda mean you have to multiply the length by 4, surely it...
