Question

One tuning fork completes 1000 oscillations in 5 seconds, its frequency is:
(A) 1000 Hz
(B) 0.005 Hz
(C) 200 Hz
(D) 5000 Hz

Answer 1

Answer:

(C) 200 Hz

Step by step explanations:

As given in the question :

Number of oscillations = 1000 [Given]

Time taken = 5 seconds [Given]

As we know that , formula for frequency is as follows:

$Frequency\ =\ \dfrac{Number\ of\ oscillation}{Time\ taken}$

$Frequency\ =\ \dfrac{1000}{5}$

Frequency = 200 Hertz .

Hertz is the unit of frequency . Which is written as Hz.
