Two point sources are vibrating in phase producing two-dimensional water wave interference. the first antinodal line on either side of the central maximum will occur at locations where the path difference of the arriving waves is: question 9 options: a) 1/4 î» b) 1/2 î» c) 3/4 î» d) î» e) 2î»

For all antinodal positions we know that

now we also know the relation between phase difference and path difference

now we will have

now from above equation we will have

now for the first anti node position

N = 1

Option D is correct

the answer to this question is 60 n

the answer is ampere

the ampere is used to measure electricity. an ampere is a unit of electric current equal. a unit of measure for the flow of current in a circuit. one ampere is the amount of current flow provided when one volt of electrical pressure is applied against one ohm of resistance.
