No, a movie projector uses a convex lens.
no Michael Jackson did not use any of the moves from the movie Greece they were all his own dance moves

Book/Movie 2. Polyjoice Potion also plays an important role in book/movie 4 and 7.
to tell what the movie is about
projector have concave or convex
since you need to show the image on a big screen so you require a diverging lens i.e. a concave lens
A concave lens is thinner at the centre. People who are short sighted often use a concave lens to help them see better.
You would use a convex lens.
Convex Lens
Convex lens because i said so
Convex lens because i said so
Use a magnifying lens. (concave)
To make the projector image smaller, you can adjust the lens by moving it closer to the projector. This will focus the light and reduce the size of the image displayed on the screen.

Concave lensss
Your are mixing properties. Converging lens is always thicker in the centre and thinner at the edges. The other cathegory is the geometry of shape of the surfaces of the lens. Convex means that the shape is similar to the outer surbace of a sphere, concave means that the shape is similar to the iner surface of a sphere (or: convex = lower side of a spoon as we use it for sampling a soup; concave: upper (inner) shape of the spoon). A double convex lens is always a converging lens. A plano-concave lens is always a diverging (not converging) lens. A convexo-concave lens is the most usual shape of a lense used in spectacles. It can be either converging or diverging, depending on the radii of the surfaces.
