According to the question, the object is placed at 2F
The ray diagram is shown in the figure attached.
According to the figure:
Object AB is at 2F₁
First, we draw a ray parallel to principal axis.
So, it passes through focus after refraction.
We draw another ray which passes through optical center.
So, the ray will go through without any deviation.
Where both refracted rays meet is point A' and the image formed is A'B'
This image is formed at 2F₂
We can say that:
- Image is real.
- Image is inverted.
- Image is exactly the same size as the object.
 
        
             
        
        
        
Yes yes ! How right you are ! Truer words were never spoken.
        
             
        
        
        
Answer:
he maximum frequency occurs when the denominator is minimum
  f’= f₀  
Explanation:
This is a doppler effect exercise, where the sound source is moving
            f = fo  when the source moves towards the observer
      when the source moves towards the observer
            f ’=f_o   Alexandrian source of the observer
  Alexandrian source of the observer
the maximum frequency occurs when the denominator is minimum, for both it is the point of maximum approach of the two objects
           f’= f₀
