This experiment revolves around using light rays and contacts. The experiment also discusses different properties of light rays. This test uses different lenses and measurements to produce images and observes distinct techniques to receive the image placement. Question and Answers:
1 . Use important computer data to verify the Law of Reflection and then use Snell's Law to calculate the refractive index for water (nw). The information showed the fact that value of theta in both the tanks were roughly same hence proving legislation of expression.
Value of Refractive index of drinking water for reservoir 1= 1 ) 68
Benefit of Refracive Index of water for tank 2=1. 35
installment payments on your What is the focal entire lens used in section 1 . 3 " Focal LengthвЂќ of your manual? Can you imagine from the image seen, in case the lens applied was converging or diverging?
The focal length of the zoom lens used is usually calculated to get 31 logistik. The contact lens used in the experiment was obviously a converging lens as the image was
3. Calculate the central length of the offered converging lens based on the measurements of s and s ' and slender lens equation. Tabulate the results (for all the three trials). Assess ratios with the image and object ranges and levels for three object ranges to showв€’(s' / s) = (h' / h) is true. Pull a ray diagram and have absolutely the different lengths for one trial.
The equation can be verified by using the 1st trial in the experiment. -(310)/(140) = (950)/(430)

4. Utilize parallax technique described in the lab manual to determine the central length of the contact lens. Compare this length for the previously computed values.
The importance of the focal length employing...
