A double-slit apparatus with 6 × 10-5 m separation between the slits is illuminated with 490 nm coherent light. A viewing screen is located 2.1 m from the slits. Only Consider fringes on one side of the central maximum. What is the linear distance between the first dark fringe and the second dark fringe (measured in mm)? 

A person has a far point of 200 cm. The distance from the cornea-lens to the retina is 1.8 cm. Suppose the eye’s power of accommodation is 3 diopters. What is the refractive power of eyeglasses should be used so the person can see objects as close as 20 cm clearly? Ignore the gap between the eyeglasses and eyes.

Consider an experiment using a diffraction grating with 3000 lines/cm, a screen 2.5 m away, and a 440-nm wavelength beam of light. How many bright fringes will be observed on one side of the central maximum? Noe that the answer is an integer.

You need to use a 20-cm-focal-length lens to produce an inverted image twice the height of an object. At what distance from the object should the lens be placed (measured in cm)?

Find the derivative of the function . Simplify your answer.​

A monochromatic laser beam illuminates a double-slit apparatus with a slit separation of 6×10-4 m. The interference pattern is formed on a screen that is 1.2 m away from the slits. If the distance between the eighth bright fringe and the second bright fringe on the screen is 6×10-3 m, what is the wavelength of the laser beam (measured in nm)?

A certain slide projector has a lens of focal length 15 cm. This lens forms an image measuring 100 cm × 100 cm on the screen when a slide whose dimensions are 5 cm × 5 cm is being magnified. How far from the lens should the screen be placed? Express the answer in cm.
