accurately describe the interactions. the wave ths of te than are of a meter), the ra model det the order of a millionth This laboratory will half is INVESTIGATION 1: A POINTs OF LIGHT object, When light is emitted or reflected by a each po soure% light how from a space. The of a tiny while exactly is small enough to be a good approximat Prediction 1-1: Light from a point source spreads out in every on the definition of is as the shri per unit area perpende how a point source will change as you increase your distance from Be as quantitative as you can, To test your prediction, you will need miniature light bulb power supply holder for light bulb computer-based laboratory system RealTime Physios Light and optics experiment con fles meter stick Activity 1-1: Light Intensity Around a Point Source Let's look at light coming a point source at different positions atond point source. Todo from use light sensor that measures thelight incident you light detecting element (called a intensity on the surface of its is associated with the brightness of the light. 1. Mount the light bulb its holder, and connect it to the power supp 2. Connect in the light sensor to the computer interface, and open the called Point display intensity. Use the meter stick to the light sensor 2.5 cm from the you pointed straight toward it. Move the sensor slightly side to get a maximum reading. The record the intensity readingin tensity in your sensor probably measures illumination in a unit called ur light white For unit refers light. our in amount of light emitted by theExplanation / Answer
Answer 3
The prediction is
The intensity decreases with distance
4)It is valid also as I=power/(4*pi*r*r).so as r increases,I decreases
