. An interference pattern is obtained by these beams. The ratio of the intensities of maximum to minimum is
A
B
4: 1
C
3: 1
D
Text Solution
Verified by ExpertsThe correct answer is:
B
To find the ratio of the intensities of the maximum to the minimum in an interference pattern formed by two monochromatic light beams with intensity ratios of 1:9, you use the formula:
Given that the intensity ratio is 
, we have 
and 
.
Calculate 
and 
:
Substitute these values into the formula:
Thus, the ratio of the intensities of the maximum to the minimum is 
.
