Transverse And Longitudinal Waves

Step 1: Use the formula for self-inductance.
The self-inductance of a coil is related to the flux , the number of turns , and the current by the formula: Rearranging the formula to solve for :
Step 2: Substitute the given values.
We are given:
- ,
- ,
- .
Substituting these values into the formula:
Final Answer: .

Concept:
Physics - Wave Motion and Wavelength.
Step 1: Define Wavelength ( ) for longitudinal waves.
For a longitudinal wave, the wavelength is the distance between two consecutive points in the same phase. This is typically measured as the distance between two consecutive compressions or two consecutive rarefactions.
Step 2: Analyze the wave structure.
One complete cycle of a longitudinal wave consists of one compression followed by one rarefaction. [Image of a longitudinal wave showing compression and rarefaction]
Step 3: Calculate the distance between adjacent opposite phases.
Since a full cycle (compression to next compression) is , the distance from a compression to the midpoint of the next rarefaction is exactly half of that cycle. $ $
