Question

1. magnification can be calculated by multiplying the eyepiece magnification to the objective lens magnification. this means the object is seen however many times larger under the microscope than in real life! for instance, if an eyepiece is 15x and you are viewing the 10x objective lens, the object would appear to be 150x the size. (ex. 15 x 10 = 150) if the eyepiece on our microscopes are 10x, what objective lens should we use to see something 400x the size?

Explanation:

Step1: Definir la fórmula de magnificación

La magnificación total $M$ se calcula como $M = M_{ojo}×M_{objetivo}$, donde $M_{ojo}$ es la magnificación del ocular y $M_{objetivo}$ es la magnificación del objetivo.

Step2: Reorganizar la fórmula para encontrar $M_{objetivo}$

Dado que $M = M_{ojo}×M_{objetivo}$, entonces $M_{objetivo}=\frac{M}{M_{ojo}}$.

Step3: Sustituir los valores dados

Tenemos que $M = 400X$ y $M_{ojo}=10X$. Sustituyendo en la fórmula: $M_{objetivo}=\frac{400}{10}$.

Step4: Realizar el cálculo

$\frac{400}{10}=40$.

Answer:

40X
