60-Light of wavelength 620nm falls on a double slit system immersed in water. It may form an interference pattern on a barrier 2.0 m away about the same water tank. What is the distance between the maximum central value and the maximum value of the second order appearing on the barrier. If the distance between the two holes is 0.5mm?

Difference between Seiemic retledian and repraction:

5) A person is looking to the horizon, sees a building of height 25 m. What is the least height of this building can be seen from the same position if the refraction is neglected?

8 In a stereo pair, which of the following statements is true (multiple choice questions) A. The larger the horizontal parallax, the closer the distance B. The higher the degree of refraction, the less the total number of images required C. The overlap is between 0 and 1 D. Transverse parallax can be used to measure the depth of field

What is the effect of factor (K) on the moment magnifications?

X Incorrect. Determine the expected diffraction angle for the first-order reflection from the (310) set of planes for BCC chromium when monochromatic radiation of wavelength 0.0703 nm is used. The atomic radius for Cr is 0.1249 nm. i 42.8 degrees

EDM 1) A line was measured by EDM found 4032.32 m, what is the probable error in this distance if the EDM precision is + (2 mm+3 ppm)? 2) The modulation frequency of a red laser beam (A=0.6328 µm) is 24 MHz. This beam travels through the atmosphere, the temperature of which is 26°C and the atmospheric pressure 1011.92 hPa. What is the modulated wavelength of the light? (Answer 2=12.4879 m) 3) A slope distance of 204.834 m was determined by EDM, the instrument and prism having been set up 1.645 m and 1.873 m respectively above their stations. The altitude angle between the stations was later measured as 2°17'40", the instrument station being the higher on the two. Calculate the horizontal length of the line. (Answer 204.679 m)

Define the term the Photon Rate?

Consider the system showed below placed in air. The lens is made fromglass with an index of refraction of 1.50.Now suppose that the system is submerged in water. Find the locationof the final image

The focal length of the object glass of a tacheometer is 200 mm, the distance between the vertical axis of the tacheometer and the optical centre of the object glass is 100 mm and the spacing between the upper and lower line of the diaphragm axis is 4 mm. With the line of collimation perfectly horizontal, the staff intercepts are 1 m (top), 2 m (middle), and 3 m (bottom). The horizontal distance (m) between the staff and the instrument station is
