WebHowever wavefront analysis provides a precise quantitative evaluation of the all optical system and related aberrations, even under a less than optimal seeing. Below, first row … Webwavefronts emitted by the loudspeaker. The parts of wavefronts A and B in water are not shown. Wavefront C has not yet entered the water. The speed of sound in air is 340 m s and in water it is 1500 m s. The wavefronts make an angle θ with the surface of the water. Determine the maximum angle, θ, at which the sound can enter water.

IMAGE DISTORTION. As a wavefront aberration, image distortion is caused by the change of magnification with the incident angle, with the actual wavefront being formed tilted with respect to a perfect (Gaussian) reference sphere. It is a consequence of the light cones for oblique angles coming in at a different angles, and using different ...
