Answer 1

To view a specimen at 40X magnification, begin with turning on the light, secure the specimen on the stage, start with the 4X objective lens, focus using the coarse then fine focus knobs as you increase magnification, switch to the 40X objective, and adjust using fine focus knob to precisely focus the image.

Step-by-step explanation:

To view a specimen at 40X magnification on a microscope, there is a specific sequence of steps that should be followed carefully to avoid damage to the microscope and to ensure a clear image of the specimen. Here is a guide with the correct order of steps:

1. 
   
3. 
   
5. 
   
7. 
   
9. 
   
11. 
    
13. 
    
15. 
    
17. 
    
19. 
    

Throughout this process, refrain from using the coarse focus at higher magnifications to prevent damage, and always make adjustments in light and focus gradually to achieve the best possible image.
