The curve of a convex lens is outward, whereas the curve a concave mirror at the bottom is inward. It is important to note that convex shapes do not have to be smooth rounded shapes like that of the convex lens. Convex shapes are those which have no internal angles greater than 180°....
Images created by convex mirrors are also virtual and upright in relation to the object. Where are F and C located in a convex mirror ray diagram? Drawing the original sphere from where the curved mirror was built, C is the center of curvature and coincides with the center of the sphere....
The parabola is a classic example of a concave curve. It is a symmetrical curve that has a U-shape. The equation of a parabola is y = ax^2 + bx + c, where a, b, and c are constants. If a is negative, the curve will be concave. If a is positive, the curve will be convex...

Convex Examples Let’s get back to the example of Joe and his image on the spoon. Now, Joe sees his reflection on the back side of the spoon. His image is not upside down as before but, it appears much bigger than the usual image on a plane mirror. ...

total internal reflection. it is the phenomenon responsible for optical illusions like a mirage and also the reason for diamonds to shine. in this session, let us know more about the total internal reflection. table of contents: what is total internal reflection? formula of total internal ...
Now the focal length only depends upon this radius of curvature and it's justrdivided by 2. K? Really easy to remember. The focal length of a mirror, half the radius of its curvature. K? Once you know the focal length for any spherical mirror we have the mirror equation to determine...

(e)Unpolished side of a mirror Ques. To a distant observer, the light appears to be coming from somewhere below the ground. The observer naturally assumes that light is being reflected from the ground, say, by a pool of water near the tall object. Such inverted images of distant tall obj...
