Fast pls solve this question correctly in 5 min pls I will give u like for sure Aka A pair of glasses is designed for a person with a far-point distance of 3 m so that she can read street signs 31 m away. (The far-point distance is the distance from the eye at which you are just able to properly focus a distant object.) (a) If the glasses are to be worn 1.0 cm from her eyes, what is the needed focal length? (b) Compare this focal length (find the percent difference) to the focal length she would need if she chooses a style of glasses that fit on her face so that the lenses are instead 2.0 cm away from her eyes.

Applications Of Reflection Of Light
When a light ray (termed as the incident ray) hits a surface and bounces back (forms a reflected ray), the process of reflection of light has taken place.
Sign Convention for Mirrors
A mirror is made of glass that is coated with a metal amalgam on one side due to which the light ray incident on the surface undergoes reflection and not refraction.
