![]() ![]() AT LEAST HOW TO GET STARTED?ĬAN SOMEONE PLEASE HELP ME WITH THIS QUESTION. Since Light Intensity is a result primarily based on the number of photons that make up the light, we can write the equation above by presenting the real reason as below: However, both equations above are valid for targets that are not in motion relative to light source. Using the relative light intensity, when both polarizer and analyzer are in the optical path and at zero degrees, as the reference intensity use the equation (I Io cos2) to calculate theoretical intensity at 30 and 45 degree angles. unitsĬAN SOMEONE PLEASE HELP ME WITH THIS QUESTION. There is the following equation in line with this rule. When calculating radiance received by a detector, refers to the solid angle subtended by the source as viewed from that detector. ![]() The maximum rate is determined by the other factors involved. When calculating the radiant intensity emitted by a source, refers to the solid angle into which the light is emitted. Problem 1: Calculate the intensity of a wave whose power is 25 KW and the area of cross-section is 35×10 6 m 2 Answer: Known measures are, P 25 KW 25×10 3 W, A 35×10 6 m 2. Increasing the light intensity increases the rate of photosynthesis, provided plenty of carbon dioxide and water are available. Units Relative light intensity (Φ = 90Ëš) 4 Arb. Let us discuss the questions related to intensity. Relative light intensity (Φ = 0Ëš) 970 Arb. Solar radiation in space The energy radiated on an object in space decreases as the object moves further away from the sun. Relative light intensity (Both polarizer and analyzer in the optical path, angle at 0Ëš) 980 Arb. c: speed of light 3 x 108 m/s T: temperature of black body (K) K: Boltzmann’s constant 1.38 x 10-23 (J/K) At the surface of the sun, T 5,800 K, resulting in w 5.961 x 107 W/m2. Relative light intensity (Only the polarizer in the optical path, angle at 0Ëš) 1329 Arb. How to calculate the position of the sun is described simply at. Relative light intensity of the laser beam (No polarizer or analyzer in the optical path) 1836 Arb. The sunlight intensity is the cosine of the suns elevation angle. Compare the calculated values with your measurements at these angles. Do calculated and measured values agree? What is the percent difference? Using the relative light intensity, when both polarizer and analyzer are in the optical path and at zero degrees, as the reference intensity use the equation (I I o cos 2) to calculate theoretical intensity at 30 and 45 degree angles. Using the relative light intensity, when both polarizer and analyzer are in the optical path and at zero degrees, as the reference intensity use the equation (I = Io cos^2) to calculate theoretical intensity at 30 and 45 degree angles.
