Investigations in Light Intensity Change through Angular Displacement Guiding Question How does the intensity of light change as the angle of incidence to the light source increases? Prediction of Results Predict what you think will happen and what type of equation and graph might best fit the data representing the intensity of a light as the angle of incidence increases. Objective After completing this lesson‚ a student should be able to analyze light intensity striking a surface at varying

Automatic street light monitoring using IR and LDR Abstract Street lights are generally switched ON and OFF by the electricity department. A separate person is appointed to take care of these activities without any fail. A part from this if irrespective of the season i.e. whether it is summer or Winter the Street lights are switched ON at the same time in the evening around 6:30 pm and switched OFF at around 6:00 am. And we know that it will be more sunny in summer season with enough light up to 7.00

Hypothesis (Null): There will be no effect upon different distance intensities of light on the terrestrial isopods. IV: The different distance intensities of light at specified lengths (1 meter‚ 2 meter‚ and 3 meters) DV: The number of terrestrial isopods (rolypolies) on the unlighted side on the petri dish. Control: The unlighted side of the opened up petri dish. Purpose: To determine the light sensitivity of terrestrial isopods (rolypolies) in different levels of lighted environment. Number

dioxide‚ water‚ and light then release oxygen back into the air. This process happens because of the movement of hydrogen to the hydrocarbons that are produced during photosynthesis. The discovery of photosynthesis is attributed to Dutch scientist Jan Ingenhousz who was the first to find that light is necessary to the process‚ it happens in the green parts of the plant‚ and that the product of photosynthesis is released into the air. The first and second part of the lab will

the relative intensities of light at various horizontal distances from the lamp. The light detector (photocell) will enable us to make light intensity measurements that are more precise than those made with the human eye. The photocell converts light intensity to an electrical potential difference‚ which can be measured with a voltmeter. Using our measurements made from numerous elevations above the table‚ we assumed voltmeters were proportional to the intensity of light and observed a relationship
