Question

microscope of power 1000x can make things appear 1000 times larger when placed under it how large will an object of diameter 3*10^-4 mm appear when placed under it

Answer 1

1000 = 1x10^3

Size = 3x10^-4x1x10^3

         =3x10^-4+3

         =3x10^-1

hope its right

Answer 2

Concept:

A laboratory tool called a microscope is used to look at things that are too tiny to be seen with the human eye. The study of tiny objects and structures under a microscope is known as microscopy. Being microscopic implies being difficult to see without a microscope. A microscope is a tool that may be used to examine cells and other tiny things. Through at least one lens in the microscope, an object's picture is enlarged.

Given:

Here it is given that microscope of power $1000x$ can make things appear $1000$ times larger when placed under it.

Find:

We have to find how large will an object of diameter $3*10^{-4} mm$ appear when placed under it.

Solution:

According to the question, microscope of power $1000x$ can make things appear $1000$ times larger when placed under it.

$1000 = 1*10^3$

Size $= 3*10^{-4}*1*10^3$

         $=3*10^{-4+3}$

         $=3*10^{-1}$

Hence, the object will become $=3*10^{-1}$ times more.
