INTENSITY OF SUNLIGHT The Intensity of the sunlight is measured at different timings by using Lux Meter which measures the intensity of illumination. The Intensity of light is measured in Lux which is the S.I unit of measurement of intensity of illumination of a source. The results are tabulated in the Table 4 and plotted as shown in the Figure 7. Table 4 Intensity of Sunlight Time Intensity of Sunlight(LUX) 9.15AM 54900 11.15AM 73400 1.15AM 81000 3.15AM 64500 5.15AM 35100 Figure 7 Plot of Intensity

Name: Skill Sheet 17.3 Thin Lens Formula Here you will become familiar and practice with a mathematical formula called “the thin lens formula.” This formula gives scientists a way to calculate the location and the size of an image that is produced by a lens. 1. What is the thin lens formula? When you use the thin lens formula‚ you assume that the thickness of the lens is very small compared with the distance between the lens and the object or the image. The formula applies both to convex or converging

RESEARCH: SENSORS ULTRASONIC RANGE FINDER An ultrasonic range finder sensor enables a robot to detect obstacles in its path by utilizing the propagation of high-frequency sound waves. The sensor emits a 40 kHz sound wave‚ which bounces off a reflective surface and returns to the sensor. Then‚ using the amount of time it takes for the wave to return to the sensor‚ the distance to the object can be computed. Unlike the bumper switch and limit switch that alert you when they have been hit‚ the ultrasonic

BIO Microscopy‚ Mitosis‚ and Motility Lab Discussion Questions In the Microscopy‚ Mitosis‚ and Motility lab‚ the class used the Compound Microscope. The Compound Microscope helped examine the prokaryotic and eukaryotic cells‚ observe the different stages of mitosis‚ and compare modes of motility used by protists. The light compound microscope works with the aid of lenses such as the eyepiece. These lenses help keep the focus of the light on the eye. The fine and course adjustments also assist with

Zack Kirkpatrick IMP 2 POW 2; Tying the Knots Problem Statement: A couple wants gto get married but to do so a ritual must be completed. This ritual includes 6 strings. The ends of each of these strings must be tied to one another on both ends. If the strings make one large loop they can get married‚ anything else however will result in them having to wait. The problem is whether or not hey will get married. The best way to find this answer is to find combinations of diffierent loops. Then

BIOLOGY 181 Lab # 4 Microscopy and Cells Lab A microscope is a tool that enables us to see objects and organisms that are invisible to the naked eye. Microscopes use a series of two or more lenses to magnify an illuminated image. Magnification is a measure of how big an object looks to your eye compared to “life size.” Microscopes also enhance the resolution of an image. Resolution is the ability to distinguish between two objects that are close together. Resolution can be increased using immersion

Discussion Questions 1. 2. What is a spectroscope and what is it used for? A spectroscope is a scientific instrument that is used to measure the intensity of the light at different wavelengths by calculating the amount of light energy that is being absorbed by the electrons at different wavelengths. 3. 4. 6. How might the difference in the brightness of spectral lines be explained? In other words‚ why are some lines in a spectra easier to see and appear brighter? Some lines in a spectra are easier

Science Lab Report Conclusion Ms. Seaward Jeneé S. White May 16‚ 2015 How Light Refracts Throughout Water My experimental question for my project is: Would light bend at a refractive angle after it propagates through water? The resolution to my experimental question is that light does bend at a refractive angle after it propagates through water. My hypothesis for my project is: I hypothesize that light will bend because of real world examples and experiments. One instance is light refracts

Lab #1 ‐ Introduction to the Microscopy & Observation of Prokaryotic and Eukaryotic Cells Introduction Many of the cells and organisms that you will be studying are at the lower limits of visibility of light microscopes; therefore‚ it is extremely important that you attain critical lighting and focussing. It is also important to handle the microscope competently to avoid damaging either the microscope or the preparation you are studying
