The rest is done by cutting away two upper and four under-teeth, and substituting false ones at the desired angle. But Lessard's a overbearin' son-of-a-gun all round, and he's always breakin' out in a new place.

We could talk until we're blue in the face about this quiz on words for the color "blue," but we think you should take the quiz and find out if you're a whiz at these colorful terms. Also called deviation. Origin of angle of deviation First recorded in — Words nearby angle of deviation angle of attack , angle of bank , angle of climb , angle of convergence , angle of depression , angle of deviation , angle of dip , angle of eccentricity , angle of elevation , angle-off , angle of friction.
How to use angle of deviation in a sentence My captain on the boat, Brazakka, he wanted me to do this Hemingway bit, with the white stubble, and he wanted the hero angle. Will Texas Stay Texan? Such deviation of the wave from its initial straight-line path is called diffraction.
Also, when light waves travel through media with different refractive indices or when sound waves travel through the medium of different acoustic impedances, diffraction effects can be observed.
Generally, diffraction effects are most pronounced when the dimensions of the obstacle nearly agrees with the wavelength of the wave. When light waves are diffracted by a single slit, the result is a diffraction pattern with bright and dark fringes. The central bright fringe has the maximum intensity and width. Intensity of the fringes decreases as we move along either side of the central maxima.
This is what we call refraction. Although light waves provide most of the examples for refraction, any other wave can also refract. For instance, sound waves refract when they cross two media, water waves refract depending on the depth. Refraction is always accompanied by a wavelength and speed change, which is decided by the refractive indices of the media.
Refraction of light waves is the most common observation, since they produce strange optical illusions. The formation of beautiful rainbows, splitting of white light by a glass prism, and mirages are some examples. What is the difference between Diffraction and Refraction? Both diffraction and refraction involve change of direction of waves. When a wave encounters an obstacle, bending or spreading occurs, which we call diffraction.
On the other hand, waves refract when they travel from one medium to another.
