question related to reflection
Asked by | 6th Oct, 2009, 06:12: PM
Since the mirror is rotated through 10 degree, the normal will also be rotated through 10 degree. And as it's mentioned it's moving away from the incident ray, so the new angle of incidence becomes 30 degree.
Hence the angle of reflection is 30 degree.
