Homework Statement Parallel light rays travel from air towards a glass hemisphere with radius R and index of refraction ng > nair. A top view is shown in the figure. http://img8.imageshack.us/img8/6380/parallellightrays.jpg (a) Determine where the light rays come to a focus relative to the...

Thanks a lot for the advice. This is the answer that I've come up with. Δx not directly relatable to Δy (for variable angles at constant v1) Horizontal range and maximum height are not directly relatable under variable angles at a constant initial speed because each is affected in a different...

So I really need some help with this question and thought I might try clarifying some things. The project was to create some sort of device to launch a projectile of any type a distance of 2.0m, 4.0m, and 6.0m. The device had to be able to be set at three different speeds and four different...

1. Describe the relationship (e.g. directly proportional, inversely proportional, exponentially proportional, etc.) between the following pair of variables. Makes use of formulas in your explanation: Δx(maximum horizontal range) and Δy(maximum height) (for variable angles at constant v1)...
