Concave Mirror, Focal Length and Radius Determination
The figure below shows an object O and it’s image I formed by a concave mirror. The diagram is drawn to scale.
Using a suitable ray, determine the focal length (f) and the radius of curvature (r) of the mirror.

In this thought-provoking response, the author's perspective is skillfully backed by an extensive body of comprehensive research and readily available information, offering a well-informed and compelling exploration of the subject matter.
Identify radiation B and provide an explanation for the differing deviations observed in the paths of radiations A and C as they pass through an electric field, as depicted in figure 15.
Determine the frequency of X-rays produced in an X-ray tube with a 12000V acceleration voltage, assuming full energy conversion, using Planck's constant and the charge of an electron.
Name the components labeled A and B in the X-ray tube, explain how altering the potential across P affects X-ray intensity, and describe the cause of the high temperature in the tube during operation.
