I'll tell you with an example. Say you create a sound by clapping your hands. The sound radiates in all directions, like an expanding sphere. The front edge of the wave is called the wavefront and it is spherical in shape.
1. o ray obey snail law of refraction, e ray does not obey 2. velocity of o ray is same for all direction, velocity of e ray is diffrent for diffrent direction. 3. for o ray wavefront is spherical, for e ray wavefront is elliptical. 4. ve>vo for negative crystal. 5. vo >ve for positive crystal.
They are not spherical
No, both spherical and hyperbolic geometries are noneuclidian.
Pilots and captains of ship use spherical geometry to navigate their working wheel to move it. They can measure their pathway and destiny by using Spherical Geometry.
The earth, which we live on, is approximately a sphere. It is important, therefore, to know spherical trigonometry.

Wavefront Technology Solutions was created in 1997.
"Not everyone qualifies for wavefront surgery. Prior to any surgery, your optomologist will put you through screening to ensure you are a candidate for wavefront surgery."
The incident wavefront is the crest of the wave before it hits a barrier which causes it to reflect
refraction
Wavefront is the locus (a line, or, in a wave propagating in 3 dimensions, a surface) of points having the same phase. Thus wavefront should be obtained after each period(duration of one cycle) of a signal. And wavefront is tangent to the signal at each of those pints. this concludes that: distance between two wavefront is lambda(wavelength of a signal).
Refracted Wavefront is the bending of the path of the waves, is accompanied by a change in speed and wavelength of the waves.
MONEY!!
The wavefront of the sound is spherical, so as distance increases, the intensity of the sound decreases proportionally to the square of the distance. There will be a point when the echo will not be strong enough to be detected above background sounds.
QualSight LASIK is a company that offer wavefront laser eye surgery in the United States. One can also have wavefront laser surgery from Lasik MD in Rochester, New York.
