Everyone in our class needs to build a lens optical device such as a projector, camera, copier, telescope, microscope, solar cooker, etc. We will need to include a ray tracing diagram. Has anyone ever made a simple device with lenses? What do you think will be the easiest and cheapest? Thanks

Telescopes are very easy and cheap. A microscope would be relatively easy as well. Solar cooker? Hah.
 
Any other opinions?
 
I've read some informational articles about building telescopes and it says that all you need is 2 magnifying glasses? Is it really this simple? If so, I'm going off to the store to buy magnifying glasses. =] Does anyone know where they sell cheap ones at? Thanks.
 
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...
Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .
