Find the angles of refraction for these two colors.

AI Thread Summary
To find the angles of refraction for red and blue light in a diamond, the indices of refraction are 2.410 for red light and 2.450 for blue light, with white light incident at 30.0 degrees. The equation sin(r)/sin(i) = n2/n1 can be used, where n1 is the index of refraction for air. The angle of incidence (sini) remains constant for both colors, while n2 varies. It is important to use accurate values for n2 to ensure precision in calculations. This approach will yield the correct angles of refraction for both wavelengths.

Homework Statement



The index of Refraction for a diamond for red light, 656 nm, is 2.410, while that for blue light, 434 nm, is 2.450. Suppose white light is incident on the diamond at 30.0 Degrees. Find the angles of refraction for these two colors.

Homework Equations



sinr/sini = n2/n1 = wvlngth1/wvlngth2

The Attempt at a Solution



My problem is where to start on this question. I was thinking maybe use the index of refraction for air over the red, and then figure out each angle, would that be correct? Or am I missing something?

it's two separate questions.

use ur equation sinr/sini = n1/n2.

sini is the same in both questions. only n2 changes. you solve for sinr.
 
I know about the two separate equations.. but is n1=air?
 
yeah. to be sure you get the right answer you should probably look it up in your book and use the value they give to 4 sig figs or more because the n2 values given are to four
 
Ok, got it! Thanks for the help =)
 
ur welcome.

Thread 'Variable mass system : water sprayed into a moving container'

Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...

Thread 'Struggle to understand the concept of the question (ice cube in water optics question)'

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...
