Question

You want to test the effect of light on the distribution of Artemia in your 35cm long testing chamber. If you measure the light at one end to be 10 lumens and the light at the other end to be 200 lumens, and the gradient distribution along the testing chamber is linear, what would you predict the lumens to be 10 cm from the darkest end?

Answer 1

Answer:

64.3 lumens

Step-by-step explanation:

Data provided in the question:

Length of the testing chamber = 35 cm

Light at one end = 10 lumens

Light at other end = 200 lumens

now,

since the variation is linear,

therefore, the gradient of the variation

= $\frac{200-10}{35}$

= 5.43

also,

the darkest end is the end with 10 lumens

therefore,

The lumens at 10 cm from the darkest end

= 10 + 5.43(10)

= 10 + 54.3

= 64.3 lumens
