Adentist wants a small mirror that, when 2.40 cm from a tooth, will produce a 4.0× upright image. what must its radius of curvature be? follow the sign conventions.

The radius of curvature is 6.4 cm

Explanation:

Given that,

Object distance = 2.40 cm

Magnification = 4

We need to calculate the image distance

Using formula of magnification

Put the value into the formula

Negative sign shows the image of the object is same side of object

(b). We need to calculate the radius of curvature

Using mirror formula

Put the value into the formula

Hence, The radius of curvature is 6.4 cm.

as we probably am aware that our atmosphere or air have various levels, each level has different gasses, and each gas has another porousness. at the point when the light originates from lower porousness to higher penetrability, it alters its course. with the goal that implies that when the light originates from the moon to the earth, it alters it's course a lot more occasions. it essentially implies that the state of the light piece of the moon is changed on the earth.
