The wave model of light is needed to explain many of the phenomena discussed in this chapter. which of the following can be understood without appealing to the wave model? a. sharp-edged shadows b. double-slit interference c. thin-film interference d. single-slit diffraction

the correct answer is A Sherp-edged shadows

Explanation:

The wave model describes the path of light as the propagation of a cosenoidal wave, in this case when two beams of light interact, they do so through the supervision of the cosines of each one.

In the lightning model, the light wave characteristics are not taken into account, this model is used for the so-called geometric optics, which explains many phenomena, image formation, reflection phenomena and shadow formation defined in the corners , since in this model the light is nine rectilinear from one point to another.

With this explanation we see that the correct answer is to

its c its is a mixture of gases

wavelength divides in half and speed stays the same.
