Ready-made solutions to the control №2 on Physics AN Remizov "Medical Physics" Section IV Optics!

Caution: The answers to Section V Quantum physics is not attached!

Solutions to problems are contained in files jpg, theoretical questions in doc. The answers to theoretical questions are selected from several books and websites.
Conditions in the control tasks:

Task 1: Examine the textbook AN Remizov §§ 25.1-25.4. Solve the problem.

1a. Natural light with the intensity passes through a polarizer, and then - through the analyzer. Is is the intensity of light incident on the screen positioned after the polarizer, if the angle between the principal planes of the polarizer and analyzer: a);

b); c). (Take into account that the intensity of natural light after passing through the polarizer is reduced by half).

1b. Once between the polarizer and the analyzer cuvette placed with an optically active sodium length of 1 dm, the plane of polarization to change their orientation by an angle. Considering the specific rotation equal to 66.5, find the concentration of optically active solution. To calculate use the formula where - the length of the cell,

C - concentration of the solution, - specific rotation.

Problem 2. Study the textbook AN Remizov Chapter 25.

Record the laws of reflection and refraction of light from the interface between two media

with refractive indices and. Derive mathematically and draw the figure limiting conditions refraction and total internal reflection. How are the angles of total internal reflection and refraction limit for these two environments?

Consider the specific situation: a ray of light moves in the water and lands on the border of "water-air", forming an angle with the normal to the interface. Fall if the ray in the air or it will undergo total internal reflection? Reasoned response calculation. To think.

Objective 3. Study the textbook AN Remizov §§29.1 - 29.2. Solve the problem.

3a. Monochromatic light intensity incident on the material and is absorbed so that the rate of decrease in intensity with distance (the first derivative of the intensity of the distance) is proportional to any point of x intensity has come down to her light (proportionality factor). Find the intensity of the light transmitted through the solution of the distance x  law Bugera.

3b. What is the transmittance and optical density of the solution? What optical density corresponds to a transmittance equal to: a) zero; b) unity? How to change (increase or decrease) the optical density with increasing transmittance? Output from the law Bouguer-Lambert-Beer fact directly proportional optical density concentration of the solution. This fact is used to determine the concentration of the solution by colorimetry and spectrophotometry?
