Question

g a high-speed movie of a hummingbird's wing beat shows that the period is about 0.2 s. th wings of the bird are about 4 cm long. assume the that the angular disposition of the wing tip is a harmonic oscillation what are frequency

Answer 1

5 Hz

Step-by-step explanation:

The time period is given by

T = 0.2 s

The time period of the humming bird wing is given by the time taken by the wing to complete one vibration.

The frequency of the wing is given by the number of vibrations completed by the wing of the bird in one second.

The relation between te time period and the frequency is given by

`T = (1)/(f)`

`f = (1)/(T)`

`f = (1)/(02)= 5 Hz`
