Alongitudinal wave of amplitude 3.0 cm, frequency 2.0 hz , and speed 3.8 m/s travels on an infinitely long slinky.

Incomplete question.Here is complete question

A longitudinal wave of amplitude 3.0 cm, frequency 2.0 Hz , and speed 3.8m/s travels on an infinitely long Slinky.

How far apart (the closest distance) are the two nearpoints on the Slinky that at one particular time both have the maximum displacements from their equilibrium positions?

λ= 1.9 m

Explanation:

Given Data

Amplitude=3.0 cm

frequency=2.0 Hz

Speed=3.8 m/s

To find

Distance=?

Solution

As the wavelength is a measure of distance between two Crest or Troughs in a wave the peaks should be identical.

So

λ(wavelength) = v(speed) / f(frequency)

λ= 3.8m/s / 2.0/s

λ= 1.9 m

no simpler subs form complex ones. synthesise = make

c) up is the direction the magnetic force is acting on the charge.
