The sun is 150,000,000 km from earth; its diameter is 1,400,000 km. For a science project on solar power, a student uses a 24-cm-diameterconverging mirror with a focal length of 45 cm to focus sunlight onto an object. This casts an image of the sun on the object. For the most intense heat, the image of the sun should be in focus. Part A: Where should the object be placed?

A scientist requires the construction of a diffraction-limited telescope to image small dunes on Mars. The telescope will be mounted on a spacecraft instrument platform. The spacecraft will orbit Mars at an altitude of 500 km. The dunes are 1 m in diameter (horizontal size, as seen from above). The wavelength of instrument operation is 600 nm. The large-format detector is a CCD with 4096x4096 array of pixels, where each pixel is 20x20 microns in size. The scientist requires that...

Myrtle is about to put in a contact lens. She looks at her own pupil, up close in a (flat) mirror. Her (spherical) eyeball is 2.0cm in diameter; her (circular) pupil is 0.5mm in diameter. Her pupil is 6cm from the mirror surface. She focuses her eye such that she sees her own pupil perfectly. A) The image of her own pupil ends up on her retina. What is the physical size of the imaged pupil? B) What is the...
