Question

the widths of two slits in an interference experiment are in the ratio 9:1.What is the ratio of amplitudes and intensities of light waves from them?​

Answer 1

Answer: ratio of slit width= ratio of intensities

ratio intensities=I1/I2= (a1 +a2)^2/(a1-a2)^2            were a= amplitude

so ratio of amplitudes= 2 : 1

Explanation:

Answer 2

ratio of slit width= ratio of intensities

ratio intensities=I1/I2= (a1 +a2)^2/(a1-a2)^2            were a= amplitude

so ratio of amplitudes= 2 : 1
