Question

11- The nickel's image in the figure has twice the diameter of the nickel when the lens is 2.84 cm from the nickel. Determine the focal length of the lens. 12- Problem 22.17: An electric catfish can generate a significant potential difference using stacks of special cells called electrocytes. Each electrocyte develops a potential difference of 110 mV. How many cells must be connected in series to give the 350v that a large catfish can produce? 13- The induction cooktops are getting popular because of the safety and its neat looks. How the it works? Describe the Physics of its function. 14- Example 24.1: A screen is separated from a double-slit source by 1.2 m. The distance between the two slits is 0.03 mm. The second-order bright fringe (m 2) is measured to be 4.5 cm from the centerline. Determine (a) the wavelength of the light and (b) the distance between adjacent bright fringes [563 nm, 2.25 cm] 15-Example 24.7: Monochromatic light from a helium-neon laser ( 632.8 nm) is incident normally on a diffraction grating containing 6x103 lines/cm. Find the angles at which one would observe the first-order maximum, the second-order maximum, and so forth. [22.3 degrees, 49.3 degrees, 1.14 16- Explain what is the difference between the phenomena of Diffraction and Interference of light In order to explain difference you need to describe Physics of both well

I have the answers but need to see these worked out. Thanks!
