The reflective surface is given by `y=2 sinx`. The reflective surface is facing positive axis. What is the least value of coordinate of the point where a ray parallel to positive `x`-axis becomes parallel to positive `y` -axis after reflection?

Find distance on focal plane where parallel and paraxial rays which are not parallel to optic axis, meet after reflection.

The point (3,2) is reflected in the y-axis and then moved a distance of 5 units towards the negative side of y-axis . The coordinate of the point thus obtained , are

The point (3,2) is reflected in the y-axis and then moved a distance of 5 units towards the negative side of y-axis . The coordinate of the point thus obtained , are

The cross-section of a reflecting surface is represented by the equation x^2 + y^2 = R^2 as shown in the figure. A ray travelling in the positive x direction is directed toward positive y direction after reflection from the surface at point M. The coordinate of the point Mon the reflecting surface is

If C is the reflection of A (2, 4) in x-axis and B is the reflection of C in y-axis, then |AB| is

Find the reflection of a point (3,-4) in y Axis

The point (1,-2) is reflected in the x -axis and then translated parallel to the positive diriection of x-axis through a distance of 3 units,find the coordinates of the point in the new position.
