The above solution has to be repeated again on the inside of \nthe prism just before the light comes out the other side.\n\nThe light gets refracted twice, one on contact with the prism, and\nagain before exiting the prism.  So you have to calculate the\nangle of incidence on the inside of the prism given the apex\nangle of 46 and the refracted angle of 26.36. A geometry\nproblem. Then repeat above calculation.

I will not do your homework for tou.\n\nDo a Google search on "refractive index" for both water and diamond. There is your answer.\n\n Come back if you have any points you don't understand. Asking other people to do your homework is not just dishonest and lazy it is really stupid.

If f is the focal length, i1 is the refractive index of the lens and i2 is the refractive index of the medium, then the sentence is stating that f = k*(1/(i1 - i2)) where k is some constant (of proportionality).\nI believe the equation being described is the Lens Maker's formula here: http://hyperphysics.phy-astr.gsu.edu/hbase/geoopt/lenmak.html#c1 .\nThe power P in that equation is 1/f.

The speed of light in a vacuum is the reference for refractive index.  Thus for any color, the RI for vacuum is 1.

The refractive index will be (sin50/Sin 35)Please put the values yourself as I donot have a scientific calculator

Violet is the purple part of the electromagnetic spectrum. It has a wavelength of 430 to 380 nm and a frequency of 700 to 790 THz.\n\nThese value average out at 405 nm and 745 THz.\n\nIf you square root these values, you get approximately 20.12 nm and 27.29 THz.\n\nA wave of wavelength 20.12 nm is in the Extreme UltraViolet range. A wave of frequency 27.29 THz is in the Moderate InfraRed range.\n\nSo the two answers for the square root of purple are EUV and MIR.

refractive index = 1 / sin of critical angle\nrefractive index is 1 / sin30\n1/1/2\n=2

use the formula sinA/sinB.\nA is the angle of incidence,B is the angle of refraction.\nso in this case it is sin40/sin25 = 1.52(to 3sig. fig)

bcoz DIAMOND has the highest value of refractive index\n2.41\nany little amount of light present has to pass thru diamond \nso diamond glitters all the time

Yes...\n\nThe refraction indecces\n\nn =c/v, but c = wave lenght * frequency

WL = c / frequency, where c is the speed of light.\n\nWL = 3 x 10^8  (m/s) / 6 x 10^14 (1/s) = 5 x 10^(-7) m = 500 nm\n\nThe result is compatible with green light (577 - 492 nm).

There are many types of glass. Different mixures creates different optical densities. These different optical densities will make the refractive index of glass vary. However, in GCSE 'O' Level, the refractive index of glass is usually 1.5. (hope this helps you)

Common glass contains about 70% silica (amorphous silicon dioxide or SiO2), which is the same chemical compound found in quartz, or in its polycrystalline form, sand. The other two ingredients commonly used in glass are soda (sodium carbonate Na2CO3) and lime (calcium oxide (CaO). Silica must be heated to 2000 degrees Fahrenheitin order to be melted.\n\nIn order to make glass into a lens, lanthanum oxide is added to the mixture to give the lense a gives glass a high refractive index and low dispersion. Most lenses for glasses are not made of glass however, but rather of a plastic known as CR2 or of polycarbonate.

when looking into a bowl of water. Air has a refractive index of about 1.0003, and water has a refractive index of about 1.33. If a person looks at a straight object, such as a pencil, which is placed at a slant, partially in the water, the object appears to bend at the water's surface. This is due to the bending of light rays as they move from the water to the air. Once the rays reach the eye, the eye traces them back as straight lines (lines of sight). The lines of sight intersect at a higher position than where the actual rays originated. This causes the pencil to appear higher and the water to appear shallower than it really is. The depth that the water appears to be when viewed from above is known as the apparent depth.

For blue light'\nd Sin th = 2W        W is wave length\nFor a minimum \nd Sin th = (2n+1)W'/2\nSo,  2W=(2n+1)W'/2\nW'=4W/(2n+1)\n  =1440/(2n+1)\nBy putting various values for n , I find that only for the valu n=1, W' is within the vivible range,\nW'=480 nm

I believe it's the percent of light that bounces back and doesnt go through. Like a mirror reflects 95% of light. Dunno could be how much a material bends light, like water, cant remember.

hi dude!\ni'll give u only the unworked answers\nwavelength of light i the cornea is 193/1.376 nm\nand the frequency would be 3*10^8*1.376/(193*10^-9) hz\ni hope i'm not too late!!
