Explanation

• Holography is a unique photographic image without the use of a lens.
• It is a recording of an interference pattern that uses diffraction to reproduce a 3D light field.
• This recorded interference pattern actually contains much more information than a focused image and enables the viewer to view a true 3D image that exhibits parallax.
  
• That is, the image will change its appearance if you look at it from a different angle,
•  just as if you were looking at a real 3D object.

Explanation

To find the range (d) of a TV transmitter antenna, we use the line-of-sight formula:

d ≈ √(2 × h × R)  

Where:  

- d = distance to the horizon in kilometers  

- h = height of the antenna in kilometers  

- R = radius of Earth ≈ 6371 km  

Convert height:  

h = 100 m = 0.1 km  

Now plug in:  

d ≈ √(2 × 0.1 × 6371) ≈ √1274.2 ≈ 35.7 km  

So, the range is approximately 36 km
