What happens when light reflects off a mirror? What is the difference between refraction and dispersion? When does refraction occur? What is the index of refraction of a clear material if a minimum of 150 \ nm thickness of it, when laid on glass, is needed to reduce...
For the special case where the light starts inside the material with the higher of the two indices, we find that there is an angle θ1 beyond which the equation cannot be solved. This happens when the expression inside the square brackets is greater than 1. The value for θ1 where the ...
A lens works by refraction: it bends light rays as they pass through it so they change direction. (You can read a full explanation of why this happens in our article on light.) That means the rays seem to come from a point that's closer or further away from where they actually ...
What determines the color of an object? A green pigment tends to most reflect which color (wavelength)? a. yellow b. red c. green d. violet What color has the highest frequency? What happens to light when it is reflected? If blue light shines on red paper, what color is seen?
This happens because the degree at which light is refracted when passes through a medium, in this case, the ice crystal, is refracted depends on its frequency. The variation is called the index of refraction. Low-frequency long-wavelength red light is refracted less strongly than high-frequency...
This happens because different wavelengths of light, thus different colors, experience a different degree of refraction when they pass through a prism. This means that lunar halos can be very lightly tinted with rainbow colors, longwave red light on the inside, and shortwave blue light on the ou...
arise from that well of information collected over our lifetimes. When the brain sends stress signals to the gut, it's likely because the brain is drawing on a previous memory tucked far back in the mind. This thought process happens so quickly that, in most cases, we don't even notice...
the blue/violet will be overcorrected and the red will be undercorrected. This is the same thing that happens with an ED Doublet "Apo." The lenses can only correct the spherical aberration for one color and the the colors on either side of that band will be either under or overcorrected...
I've seen chromatic aberrations through binoculars and it's not pretty. My dad has this really old pair of binoculars which belonged to one of his great uncles or something like that. The chromatic aberration is to the point where it obstructs your view, but my dad just won't give up ...
If you look closely at what happens as the light wave enters the prism in the second diagram, you will notice that it bends down. This bending occurs because the light travels faster through the air than it does through the prism. When the lower portion of the wave enters the prism, it...
