Question

two tuning forks have frequencies 450 hz and 454 hz h respectively on sounding this forks together, the time interval between two successive maximum intensities will be .... a .1 upo4 Second
B. 1 upon 2 second
C .1 second
D.4 sec​

Answer 1

Answer:

Answer is (c) 1 sec

note- other options is wrong (a) 1/4 s (b) 1/2 s

(d) 4 s

Answer 2

Given :

Frequency of tuning fork 1 (f₁) = 450 Hz

Frequency of tuning fork 2 (f₂) = 454 Hz

To find :

The time interval between two succesive maximum intensities

Solution :

• Beat frequency of tuning fork = I f₂-f₁ I

                                                 = I 454 - 450 I

                                                 = 4 Hz

• The time interval for 4 maximum intensities will be 1 sec

• The time interval for 1 maximum intensity  = 1/4 sec

The time interval between two succesive maximum intensities will be 1/4sec
