Agiven individual is unable to see objects clearly when he is beyond 80 cm. what power lens should be used to correct this problem? a) -1.25 diopters b) -3.68 d c) -11.650485 d d) -0.2 d e) -15.686275 d

Explanation:

The person will have normal eye if he can see objects placed even at infinite  

distance. He suffers from short shortsightedness. He can not see beyond 80 cm. He requires diverging lens ( concave lens ) the focal length of which will be 80 cm , because in that case, light coming from infinity will appear to be coming from 80 cm so he can see them.  

Focal length in cm = - 80cm

Power =- 100/80 D = -1.25 Diopters

the focus of lesson 1 is newton's first law of motion - sometimes referred to as the law of inertia. newton's first law of motion is often stated as. an object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.

explanation:

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.

not copied too! hope this !

h o h o hope you have a merry christmas!
