Parfocal is the term used to describe a microscope that maintains focus when the objective lenses are replaced.
<h3>
What is the name of the objective lens ?</h3>
For observing minute features within a specimen sample, a high-powered objective lens, often known as a "high dry" lens, is perfect. You can see a very detailed image of the specimen on your slide thanks to the 400x total magnification that a high-power objective lens and a 10x eyepiece provide.
The four objective lenses on your microscope are for scanning (4x), low (10x), high (40x), and oil immersion (100x).
The first-stage lens used to create a picture from electrons leaving the specimen is referred to as the "objective lens." The objective lens is the most crucial component of the imaging system since the quality of the images is determined by how well it performs (resolution, contrast, etc.,).

This is an example of slowing down because you encountered heavy traffic or just got tired.
Also, the numbers show acceleration.
Answer:
Density of air decreases.
If the amplitude of the wave increases by 4 times, the intensity will increase by 16 times. Option B is correct.
<h3 /><h3>What is the relation between the
intensity and the
Amplitude?</h3>
The intensity is directly proportional to the square of the amplitude of the wave.
Where,
- Intensity
- Amplitude
- constant
Thus, if the amplitude of the wave increased by 4 times,
Therefore, if the amplitude of the wave increases by 4 times, the intensity will increase by 16 times.
