In this experiment, we will be determining the properties of a medium that affects the Light Reflection and Refraction In Liquids. We shall also be determining up to what extent these properties of a medium affect the properties of light and will also be understanding the concept of light physics.
To determine the properties of a medium that affects the Light Reflection and Refraction In Liquids.
1. In refraction, when a light ray travels from rarer to a denser medium, it bends toward the normal, while when it travels from denser to a rare medium, it bends away from normal.
2. If the medium changes, the speed of light also changes.
1. A Tripod
2. A laser light with 630 to 680 nanometers of wavelength
3. A table
4. A container of liquid
5. A wall with a measuring poster
6. Watery liquid
7. Oily liquid
Step 1: Divide the experiment into parts. In the first part, we will be testing the reflection of light, and in the second part, we will be testing the refraction of light.
Step 2: Choose a controlled environment to perform the experiment efficiently.
Step 3: For the first experiment (reflection of light), set up a tripod, a light beam of wavelength 630 nm to 680 nm, a container filled with water, and a wall with a measuring poster on it.
Step 4: The setup is ideal as it will be easier to demonstrate the trigonometric functions that will be needed to calculate the result.
Step 5: Create the same setup for the second experiment as well (refraction of light). The only difference will be measuring posters. Instead of keeping the measuring poster on the wall, place it underneath the container.
Step 6: For both the experiments, shine the light on the container at an angle of 45 degrees.
Step 7: Perform this experiment with different liquids available in your home.
Step 8: Record your observations.
Reflection and Refraction of Light
1. We obtained our results in two parts. In the first part, we obtained the actual refraction and reflection of light. While in the second part, we obtained the properties that affected the refraction and reflection of light.
2. For the first experiment (reflection of light), all the liquids reflected light at the same degree of angle.
3. Therefore, the test of light reflection was constant.
4. For the second experiment (refraction of light), all the liquids are affected by the viscosity.
5. Therefore, the test of refraction was not constant.
1. The result of the experiment puzzled the experimenter because of the variance in the result.
2. The refraction, intensity, and reflection of light got affected by the color, viscosity, and opacity by increasing and decreasing the angle of intensity, angle of refraction, and angle of refraction.
3. We obtained a constant result in the first experiment, and properties did not affect the reflection much.
4. In the refraction, we obtained the result into two groups of liquid. For oily liquid, it was on an average of 2.2cm of refraction, and for the watery liquid, it was on an average of 1.7 cm of refraction.
5. Therefore, we concluded that the properties of a medium do affect the reflection and refraction of light.
1. The wavelength of light should not be greater than 680 nm.
2. Use different kinds of liquid.
In this experiment, we determined the properties of liquid that affect the reflection and refraction of light.
