Ohhh, I see where I went wrong now. Thank you! :smile:

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...

Yes, that was right! Thank you so much for your help! :smile:

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. Homework Equations n1 sin(theta1) = n2 sin(theta2) The Attempt at a Solution I keep finding different...

Ohhhh wow, that was it! Thank you so much! I didn't even realize.

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?

Nope, I put it in exactly how I did here without rounding off the calculation of the hypotenuse.

When I put it in my calculator, I did square it... oops, just forgot to type it here. Still getting 5625.

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 3. The Attempt at a Solution I know the x-components...

Oh, that makes sense! Thank you for your help!

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.

I think I might have messed up putting it in my calculator, because now I'm getting 20.5 N.

Homework Statement A sphere of radius 10.0 cm floats in equilibrium partially submerged in water with its lowest point 5.00 cm below the water's surface. (a) What is the buoyant force acting on the sphere? Homework Equations F = pvg The Attempt at a Solution F= 1000 * v * 9.8 V=...

Awesome! Thank you so much for your help!
