A rock has a mass of 100g and it is thrown across a pond at a speed of 30ms^-1. Calculate the de Broglie wavelength of the rock and explain whether you can see the wave produced.

λ=h/p λ=h/mv λ= 6.6310^-34/0.130 λ= 2.21*10^-34m We cannot see the rock's de broglie wave because its wavelength is much smaller than that of the visible spectrum

I have an infinite number of glass blocks stacked side by side. The first block has refractive index n1, the second n2 and so on, such that n1<n2...<n(infinity). I shine a light on the stack, what angle does the ray make to the normal on the last block?


Given that a light ray enters a glass prism at angle of 50 degrees from the normal and is refracted to an angle of 30 degrees from the normal, calculate the speed of light in glass.


What is the difference between linearly, directly and inversely proportional relationships?
