A sonar pulse has a wavelength of 3.0 cm. If the pulse has speed in water of 1,500 m/s, what is its frequency?
According to the universal wave equation, a wave's velocity is equal to the sum of its wavelength and frequency.
In terms of math,
First, convert the provided wavelength between centimeters and meters.
Becomes,
Step 3: To find the pulse frequency, substitute the values you already know.
When the value is rounded to two significant figures,

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.

- How many nodes are on this standing wave? How many wavelengths are on this standing wave? What is the speed of the wave on the string? What is the wavelength of this standing wave? What is the frequency of this standing wave?
- If a spring is cut into 9 equal pieces then they r connected in series with the same mass.what will be it's frequency relative to the original frequency?my text book says that the answer is 9f.but Time period of spring does not depend on length.right?
