Homework Statement
A laser beam is incident at an angle of 30.0° from the vertical onto a solution of corn syrup in water. The beam is refracted to 22.84° from the vertical.
(a) What is the index of refraction of the corn syrup solution?
I already got the answer of 1.29.
(b) Assume that the...
Okay, so from what I understand, it changes based on the wavelength...does that mean that I would just look at the wavelength of the value of 1.33 value for water? At 589.29 nm, water has a refractive index of 1.33. The closest wavelength to that value from the ones you have would be the one at...
Homework Statement
A ray of light is incident on a flat surface of a block of gallium phosphide that is surrounded by water. The angle of refraction is 8.0°. Find the angle of reflection.

I keep finding different...
What do you mean? I thought that since sine is OPP/HYP and the opposite would be 0.400 and the hypotenuse would use Pythagorean theorem and it would be square root(1^2 + .400^2, so it would be sin(.400/(square root(1^2 + .400^2))... right?
Homework Statement
Two 1.00µC charged particles are located on the x axis. One is at x = 1.00 m, and the other is at x = -1.00 m.
Determine the electric field on the y axis at y = 0.400 m
Homework Equations
Electric Field = ke * q / r^2

I know the x-components...
Okay, I sketched it and now I'm wondering if I use half that radius of 10 cm because it's half submerged. So:
F= 1000 * 1/2(4/3*pi*(.05)^3) * 9.8 = 5.13 N. I'm not sure if I'm going off in the wrong direction now.
