Answer 1

Answer:

Given:

Distance between consecutive nodes is 25 cm

speed of wave = 300 Hz

To find:

Frequency of wave

Calculation:

In a stationary wave /standing wave, the distance between successive nodes or antinodes is λ/2

So, as per question :

λ/2 = 25

=> λ = 50 cm = 0.5 m

Now, frequency = velocity/wavelength

=> freq. = 300/(0.5)

=> freq. = 600 Hz.

So, the final answer is 600 Hz.

Answer 2

standing wave or stationary

a stationary wave is formed when two identical face travelling in the opposite direction along a straight line interference.

Question :

we have to be find frequency standing of wave

Given :

distance between two consecutive nodes is 25cm.

λ/2 = 25

λ = 50 cm = 0.5 m

solution

frequency = velocity/wavelength

= 300/0.5

= 3000/5

= 600 Hz
