What magnification will be produced by a lens of power –4.00 D (such as might be used to correct myopia) if an object is held 35 cm away? Your answer should be a number with two decimal places. Hint: you need to first determine the focal distance of the lens.
Suppose a lens of power -2.25 D (such as is used to correct myopia) is held 22.5 cm away from an object.

pls answer a & b asap thanks i will rate
Consider a room heater that uses a concave mirror to reflect infrared radiation from hot coils. The mirror has a radius of curvature of 55.0 cm and produces an image of the coils 2.70 m away from the mirror. Calculate the intensity of IR radiation in W/m2 projected by the concave mirror on a person 2.70 m away. Assume that the heating element radiates 1,350 W and has an area...

You have a concave (diverging) lens with a −30 cm focal length. The magnification produced by the lens for a particular object distance is m = 1/2 and you wish to decrease the magnification to m = 1/8. Determine the distance and direction (away from or closer to the lens) through which the object must be moved in order to accomplish this.

A concave lens has a focal length of -36 cm. Find the image distance and magnification that results when an object is placed 19 cm in front of the lens. (Use the proper sign convention for both quantities.) When an object is located 61 cm to the left of a lens, the image is formed 25 cm to the right of the lens. What is the focal length of the lens? An object with a height of 2.22 cm is...
