Question

A spherical wave with a wavelength of 2.0 mm is emitted from the origin. At one instant of time, the phase at rrr = 4.0 mm is πradπrad. At that instant, what is the phase at rrr_1 = 3.5 mm ? Express your answer to two significant figures and include the appropriate units.

1. Complete Question

A spherical wave with a wavelength of 2.0 mm is emitted from the origin. At one instant of time, the phase at r_1 = 4.0 mm is π rad. At that instant, what is the phase at r_2 = 3.5 mm ? Express your answer to two significant figures and include the appropriate units.

The phase at the second point is Explanation:

From the question we are told that

The wavelength of the spherical wave is The first radius  is The phase at that instant is The second radius is Generally the phase difference is mathematically represented as this can also be expressed as So we have that substituting values
