A cell phone has a camera with a lens diameter D = 3mm and a focal length of f = 4.25mm. (1mm = 10⁻³m.) For this problem take the wavelength of light to be 500 nm (5 × 10⁻⁷) m. Assume the sensor in the phone is 5mm x 5mm and that each pixel has a size of 2μm x 2μm. (1μm = 10⁻⁶m.)

What is the the size of meter stick on the sensor?

what is the angular size of an object which has a height of 5 mm if it is located 5m from the phone?

Thanks in advance!

A digital camera has a lens that can be approximated as a thin lens of focal length 6 mm, located a variable distance x from an image CMOS pixel plane. The pixel array has dimensions of 1000x1000 and the pixel size is 3 microns. 1. If x- 8 mm, then the image on the pixel plane is in sharp focus for an object a distance So in front of the lens. Determine So If an object at nearly infinite distance...
