Therefore the answer would be 0 degrees and 180 degrees? The book states that answers must greater or equal to one and less than 360.

Homework Statement sin 2θ = sin θ Find the solutions in degrees. Homework Equations sin 2θ = 2sinθcosθ The Attempt at a Solution sin 2θ = sin θ 2sinθcosθ = sin θ sinθ *cosθ/sin θ = 1 That's as far as I can get, and I think that is wrong. How do I procede from 2sinθcosθ = sin θ?

Can someone assist me in solving this problem?

Homework Statement An aircraft causes a horizontal layer of charged particles to be formed in the atmosphere. Radio waves are relected without phase from this layer. Radio waves of frequency 8.00 x 10^2 kHz are received at a location 12 km from the transmitter. What is the minimum height of...

For this problem I calculated 62.4 degrees, the same thing you got. As for B, I put water.

1. I think number 1 has to deal with the electromagnetic waves being refracted. 2. I know I do 3.0 x 10^8 * .700 to get the speed of light in water. Then I'm stuck. 3. The speed is 2.25 x 10^8, but I don't know how to get the index of refraction. 4. I am really lost. 5. 50 degrees as...

Can someone please help me out?.

Anyway someone could walk me through some of these problems?

Homework Statement 1. What property of light causes the sunlight to reach the Earth before the sun actually appears over the horizon? 2. What is the wavelength, in water, of blue light whose wavelength is 4.5 x 10^2 nm in air? 3.The speed of a certain liquid in a certain liquid is 3/4...
