  1. A property of spherical wave fronts is:
  1. They interact with one another to always produce positive amplitude reinforcement.
  2. They interact with one another to always produce negative amplitude cancellation.
  3. They propagate radially outward from a center source in concentric circles.
  4. They always travel at the speed of light.

Solutions

Expert Solution

ANSWER: C) THEY PROPAGATE RADIALLY OUTWARD FROM A CENTER SOURCE IN CONCENTRIC CIRCLES.

EXPLANATION:

A wavefront can be defined as a continuous locus of particles vibrating in the same phase. A ray drawn perpendicular to the wavefronts gives the direction of the propagation of the wave.

Now there are 3 types of wavefronts: Spherical, cylindrical and plane wavefront.

A Spherical wavefront is formed when a wave is produced from a point source and propagate radially in all the direction. Here we can find CONCENTRIC circles of wavefronts with the point source as the center.

It is important to note that the wavefronts are disturbances in the medium which travels with same speed as the speed of sound ​​​​​​, not speed of light.

And the waves are concentric, hence don't interact with each other. It requires at least of 2 different sources to produce an interference.

It was a pleasure answering your question. Hope this helps...

Good luck!

Genes often interact with one another. The term epistasis is applied to cases in which one gene alters the expression of another gene that is independently inherited. In Labrador retriever dogs one gene locus is involved with production of melanin pigment: B (black) and b (brown) are its two alleles. Another gene locus determines whether the melanin produced is actually deposited in individual hairs as they grow (E) or not deposited (e). Any dog with at least one dominant allele...

Write a function ‘filter_wave(wave,n)’ and this will produce a new wave which is a smoothed version of the input ‘wave’ adhering to the following rules. The input parameter n will be explained later in part 2. • In the new wave, for every position i, it is the weighted sum of three positions of the original wave. More preciously, the new wave value in position i will be equal to new_wave[i] = wave[i-1] * 0.2 + wave[i]*0.6 + wave[i+1]*0.2 •...
