1.	Light of wavelength 5000 Å falls on a plane reflecting surface. What are the wavelength and frequency of the reflected light ? For what angle of incidence is the reflected ray normal to the incident ray?
Answer» Given `lambda=5000 Å =5xx10^(-7)m` The wavelenght and frequency of reflected light remains the same. `therefore` Wavelength of reflected light, `lambda=5000Å` Frequency of reflected light `upsilon=(c)/(lamda)=(3xx10^(8))/(5xx10^(-7))=6xx10^(14)Hz` The reflected ray is normal to incident if angle of incidence i=45
