In the above figure a (blue) light ray from the top of an object is striking a concave mirror, which reflected (red) ray results? The focal point is the orange dot on the left.
In the above, which is the correct exit ray?
In the above which is the correct exit ray? The green square on the left is the focal point.
In the above a light ray is incident on a convex mirror. Which is the correct exit ray? The green squares are the focal point.
In the above a light ray is incident on a convex mirror. Which is the correct exit ray? The green square on the right is the focal point.
The above figure shows a light ray being (totally) internally reflected by the slanted surface of a prism. What is the minimum value for the index of refraction of the prism for this to occur as shown?
In the above a light ray is incident on a thin converging lens (thick vertical blue bar). Which is the correct exit ray? The green squares are the focal points.
In the above a light ray is incident on a thin converging lens (thick vertical blue bar). Which is the correct exit ray?
In the above a light ray is incident on a thin diverging lens (thick vertical red bar). Which is the correct exit ray?
The radius of the first surface, R1, and the radius of the second surface, R2 of the lens at the left are
