Worked Solution & Example Answer:When green light is shone into a red solution, such as blood, some of the light is absorbed, some is reflected and some passes straight through - Junior Cycle Science - Question 12 - 2019
Step 1
In the space below, draw a graph of the results obtained.
Answer
To create a graph of the results, plot the number of drops of food coloring on the x-axis and resistance on the y-axis.
-
Plot the following points:
- (0, 1.0)
- (1, 1.5)
- (2, 2.0)
- (3, 2.5)
- (4, 3.0)
- (5, 4.0)
- (6, 4.5)
- (7, 5.0)
-
Once all points are plotted, connect them with a smooth curve or line that reflects the trend of the data.
-
The resulting graph should show an increasing trend, indicating that as the number of drops increases, resistance also increases.
Step 2
State one conclusion which is supported by the results.
Answer
The results indicate that resistance increases with the number of drops of food coloring added to the solution. This suggests that a higher concentration of food dye leads to more absorption of the green light, resulting in a higher resistance in the LDR.
