- Some people view bacteria specimens with a 100x objective lens in order to see the smallest details.
- Others may use a 10x objective lens for more general purposes, such as examining stained slides or pictures.
- And still others may use a 40x objective lens to gain maximum resolution when viewing images of thick samples.
It is important to choose the appropriate magnification for your needs so that you can properly examine the specimen under study.
<h3>Why is the 100x objective lens necessary to see bacteria?</h3>
- Bacteria must, of course, be viewed at the maximum magnification and resolution possible because to their small size.
- Due to optical restrictions, this is approximately 1000x in a light microscope.
- To improve resolution, the oil immersion method is performed. This calls for a unique 100x objective.

Answer:
Heya how have you been doing
Answer:
Explanation:
given,
tuning fork vibration = 508 Hz
accelerates = 9.80 m/s²
speed of sound = 343 m/s
observed frequency = 490 Hz


![v_s = v[\dfrac{f_s}{f_o}-1]](https://tex.z-dn.net/?f=v_s%20%3D%20v%5B%5Cdfrac%7Bf_s%7D%7Bf_o%7D-1%5D)
![= 343[\dfrac{508}{490}-1]](https://tex.z-dn.net/?f=%3D%20343%5B%5Cdfrac%7B508%7D%7B490%7D-1%5D)

distance the tunning fork has fallen


=8.1 m
now, time required for the observed will be

now, for the distance calculation


=0.293 m
total distance
= 8.1 + 0.293 = 8.392 m
Answer:

Explanation:
Given
--- Surface Tension
--- Radius
Required
Determine the required force
First, we calculate the circumference (C) of the circular plate





The applied force is then calculated using;
