  parallax
- 2
  
  height
- 3
  
  parallax difference
- 4
  
  height difference
Answer: 3

Explanation:
6) Question.

The change in parallax dp introduces a change in height
Answer.
- 1
  
  $d h = \frac{(H - h) d p}{b H}$
- 2
  
  $d h = \frac{(H + h) d p}{b H}$
- 3
  
  $d h = \frac{{(H - h)}^{2} d p}{b H}$
- 4
  
  $d h = \frac{{(H - h)}^{2} d p}{2 b H}$
Answer: 3

Explanation:
7) Question.

If pB and $∆ p$ be the parallax to B and difference in parallaxes to A and B respectively, on a pair of stereo photographs having focal length f and the groung base B, the difference in their heights, is
Answer.
- 1
  
  $∆ h = \frac{p B . B f}{∆ p + p B}$
- 2
  
  $\frac{∆ p . B f}{p B (∆ p + p B)}$
- 3
  
  $∆ h = \frac{∆ p . B f}{p B (p B - ∆ p)}$
- 4
  
  $\frac{∆ P . B f}{p B ∆ p}$
