Question

What is the range of reflection coefficient for close-grained crops?

(a) 0.15-0.25

(b) 0.05-0.45

(c) 0.05

(d) 0.45-0.90

The question was asked in an international level competition.

This is a very interesting question from Water Requirements of Crops topic in chapter Water Requirements of Crops of Irrigation Engineering

Answer 1

Right answer is (a) 0.15-0.25

The explanation is: The range of reflection coefficient for different surfaces are-

Close-grained crops

0.15-0.25

Bare lands

0.05-0.45

Water surface

0.05

Snow

0.45-0.90
