Question

Shaila set up an experiment as shown below using object A. She repeated the same experiment
using objects B, C and D. The 4 objects are similar in size and thickness but are made of different
materials. She recorded the amount of light picked up by using the light sensor. What was the
aim of Shaila’s experiment?
Object Amount of light picked up (units - lux)
A 150
B 0
C 300
D 100
a. To find out how the amount of light passing through the object, affects the materials used.
b. To find out how the materials used, affect the amount of light passing through
the object.
c. To find out how the position of the light sour

Answer 1

Answer:

Light Sensor Units

Before we can properly understand light sensors and how to apply them, we need to be able to quantify light. Unfortunately, measurement of light uses some strange units. For example, lightbulbs are usually rated using lumens, but light sensors typically take measurements in lux. On top of that, both lumens and lux are based on an arcane base unit called the candela.
