I had a science experience today. It is about light and lenses.
I learned about the concave lens and the convex lens.
I used laser pointer to know what direction does the light go.
FIrst, I shone laser to a concave lens. And next, I shone it to convex lens.
And I checked the final result.
When I check the concave lens, the light dispersed.
And when I check the convex lens, the light gathered.
Because, light reflact to thicker part of the lens.
