Curvature of Wavefronts
Light can be viewed as beams travelling between points. However, from most light sources, the light radiates
outwards as a series of wavefronts. Light from a light source is bent - wavefronts of light have a property known as
curvature.
As light travels further away from its source, its curvature
decreases. Consider a sphere expanding gradually from a point,
which represents a given wavefront of light.…read more

Lenses 3
The Lens Equation
Overall, then, the formula relating the curvature of the wavefronts
leaving a lens to the curvature of the wavefronts entering it is:
The lens equation, applied to a single pixel.
where v is the distance between the lens and the in-focus image formed, u is the distance between the lens and the
object which the in-focus image is of, and f is the focal length of the lens.…read more

This is pretty awesome, thanks! 

Hamed

haha just saw this. No problem guys. Any of you need help with any physics problems let me know, I'll be happy to help. 

anushkaa

hey, thanks for the notes. Where can i find the worked solutions. Thanks 

Cameron Haswell

Hamed you're a lad man :)
