A parallel beam of light rays, which is parallel to the principal axis, hits on a convex mirror and the light is reflected. Syllabus. Advertisement Remove all ads. An object can only be seen when light rays from the object enter our eyes. This is the type of information that we wish to obtain from a ray diagram. Draw a ray diagram … The crystal is illuminated through a high numerical aperture condenser which creates the convergent light beam. Alternatively, when light from a point source located at the focal point of a lens enters the lens, it emerges as a paraxial, parallel beam of light. A parallel beam of light containing orange (610 nm) and violet (410 nm) wavelengths goes from fused quartz to water, striking the surface between them at a \(\displaystyle 60.0°\) incident angle.

Solution : Mark the princple axis, optical center, principle focus and focal length of the convex lens on the diagram. Suppose that a flashlight could be covered with black paper with a slit across it so as to create a beam of white light.
