Living Colour

by | Aug 19, 2022 | Physics, Experiments

Introduction

In this experiment, “living colour”, we will be using the wavelength of additive colours to determine the wavelength of primary colour and white light.

For performing this experiment, we will be building a machine.

Aim

To determine the wavelength of white light and additive colour by using the wavelength of primary colours,

Theory

1. There are three primary colours. Those are red, blue, and green.

2. We hypothesised that all the additive colours come from these primary colours. Not just additive color but white light also originates from primary colors.

Requirments

1. Wood

2. Reflector

3. Paint

4. Wiring

5. Dimmer

6. Red light

7. Greenlight

8. Blue light

9. Diffuser strip

10. Nails

11. Screws

12. Calculator

13. Notepad

14. Pencil

15. Camera

Procedure

Step 1: Assemble the lights, wiring, and dimming materials into the color machine.

Step 2: Blend the primary colours to obtain additive colours and also the white light.

Step 3: Add a diffuser strip for the distinction of the prism.

Step 4: Take the photos while the blending happens.

Step 5: Apply wavelength to the primary colors.

Step 6: Calculate the average wavelength of two primary colours to calculate the wavelength of additive colours.

Step 7: Calculate the wavelength of the white colour by taking the average of all three primary colours.

Step 8: Test the calculation in the machine.

Step 9: Note down your result in a notepad.

Observation

1. On taking the wavelength of primary color in pairs,, we measured the wavelength of additive colors.

2. We used the average wavelength of three primary colours to calculate the wavelength of white light, But we were unable to find any mathematical result.

Result

1. We were successful in creating the additive color by blending the primary color.

2. We calculated the wavelength of additive colours by blending the wavelength of primary colours.

3. We hypothesise that white light also comes from the primary color. But we were wrong.

4. We could not calculate the wavelength of white light using the wavelength of primary colors.

5. Therefore, it is wrong to say that the wavelength of white light can be calculated as the wavelength of additive color has been calculated.

Precaution

1. Make sure the machine is working properly.

2. Note down your calculation carefully.
