Question

Two waves of equal intensities "I" beat together, what is the maxima of the beat equal to ?
Is it 0 or infinity,or other answers......... I just couldn't get it

Answer 1

At

Answer 2

maxima=1/beat frequency, but I just couldn't get it

Answer 3

beat create from two waves of different frequencies and beat is equal to the difference of the frequencies of that two waves.
actually your maxima is also equal to the difference of two frequencies

Answer 4

but intensity will be changed if frequencies of two different waves will change. so two waves of same intensity never create any beat

Answer 5

I had initially thought about 0, but I just couldnot figure out if actually, same intensities means same frequency or not

Answer 6

intensity is directly proportional to the square of frequency of a wave

Answer 7

I think it's amplitude, not frequency

Answer 8

same intensity means same frequency and something more

Answer 9

same intensity means same amplitude too

Answer 10

What's the formula for maxima, though I know that beat frequency=difference of frequencies

Answer 11

ya u r right

Answer 12

So, what's the formula for maxima, then

Answer 13

maxima is equal to the difference between two frequencies of two different waves

Answer 14

actually maxima means loud sound

Answer 15

maxima means highest amplitude of the resultant wave

Answer 16

Thanks mate

Answer 17

resultant wave creates from two different wave

Answer 18

welcome mate
