9:40 the angle of the refracted wave has the wrong sing to it, oder ?

[@jameskellinger8314]

Please don't wave your hands--it is very distracting

[@zaozari]

Why isn't the upper green ray parallel to the focal plain, as previously explained?

[@AlsXZ]

28:55 I thought there must be a small (infinite small? ) point of light in focus but there's a spot. Why?

[@nadinhanaysha1363]

When using light microscopy, do you start from the largest or the smallest distance (between the lens and? The specimen)? Why

[@poodook]

You start with Lowest magnification and hence largest working distance.

@@poodook ok , Thank u

[@anonviewerciv]

The optics you learn in high school physics, basically.

I remember doing this as a school boy. Today it is university level education.
