Question

A wave front has the form of a        A. sine wave. B. circle. C. surface of a sphere. D. straight line.

Answer 1

The answer should be A. Sine wave

Answer 2

Answer;

Surface of a sphere

Explanation;

• A wave is a transmission of a disturbance from a given point to another. it involves the transfer of energy from a particular point to another and involves vibration of particles along the medium of transmission.
• A wave front refers to an imaginary surface of a wave that corresponds to the points of a wave that are vibrating together. Wave fronts may take three forms, namely; spherical, plane or cylindrical.
• The plane wave front takes the simplest form, such that the wave rays are parallel to one another.
• An example of a spherical wave front is when the light from the sun strikes the earth at a spherical wave front.
