Show I AUTO HEADLIGHTS ARE STUDIED BY STUDENTS An effort is be being ng made by Dr Orin of the physics department to stimulate an interest in the science and practice of illumination One phase of this work worle which is of special interest at present is the intensity and distribution of the illumination from from automobile headlights This problem has been assigned to Orson Smith Smithy a senior and an assistant in the physics department The cit city traffic regulations states state that an automobile shall shan be fitted with two headlights capable of rendering visible objects feet distant Moreover Moreover Moreover More- More over no part of the light beam shall rise above 42 12 inches from the at a distance of 75 feet Peet in front of the the automobile Mr Ir Smith is testing headlights headlights head head- r lights fitted with various lenses to determine determine de de- de termine how near these lenses conform conform conform con con- form to the traffic regulations Man Many types of lenses are sold de designed designed de- de e- e signed so the makers claim to eliminate eliminate nate glare and retain all the desirable features The tests show that some lenses absorb nearly half of the light and scatter the remainder in directions directions where It is not needed Mr Smith has constructed his testIng testing test test- ing photometer from odd pieces of apparatus apparatus ap ap- apparatus found about the physics labo |
