How can we get a rainbow from sunlight simply by placing a mirror in water?


  1. Fill the glass with water.
  2. Put the mirror into the water inside the glass at an angle.
  3. Position the glass so that sunlight shines directly at the mirror.
  4. Look for a reflection on the wall.
  5. Adjust the angle of the mirror until you see a rainbow on the wall.

How does glass make a rainbow?

Why does sunlight shining through water drops make a rainbow? Whenever light moves from air into something clear (like water or glass), it slows down just a little bit. If it hits the water or glass at an angle, it bends as it slows down. The white light of the sun is made up of all the colors of the rainbow.

Can a mirror create a rainbow?

Position your glass of water on a table and then place the mirror inside it at an angle. Take the flashlight and aim the light towards the mirror that you placed inside the glass. Watch a rainbow appear from the angle of your mirror. Adjust the angle of the mirror as you wish!

Can you make a rainbow with a LED Flashlight?

You can make this really simple and just hold a CD up to some sunlight – or shine a flashlight on one in a darkened room – and you will see a rainbow on the CD.

Can you make a rainbow with a flashlight?

Cover the flashlight with two pieces of tape leaving a slit in the middle. Shine the flashlight through the glass of water onto the piece of paper. The rainbow should appear on the paper. Play with the angle of light shining through the glass until you get a good rainbow.

What happens when the light hits the mirror in the water?

Each of these colors bends at a different angle because each color travels at a different speed inside water or glass. When you reflect the light back out of the water using the mirror, you’re reflecting the white light that has been broken up (from refraction) into the full rainbow of colors, and a rainbow appears!

What happened to the light that fell on the mirror?

When light falls on a mirror, it changes the direction of light. This phenomenon is called the reflection of light.

What happens if you point a mirror at the sun?

The light is reflected. This means that it leaves under the exact same angle as it hit the mirror. All the reflected light will therefor, by definition, go straight back at the sun.

What did you see when you shine a flashlight through the side of the glass of water?

Flashlight shining through a glass of water and milk. The light you eventually get to see when you look at it from the other side of the glass is a vivid red-orange color, which represents the white light of the sun minus the blue light that has been scattered out.

What color does the flashlight emit How does it affect the color you see on the glue sticks?

The flashlight emits white light. White light is made up of red, orange, yellow, green, blue, and violet light. Blue is the first color to scatter. Looking at the side of the glue stick, you see scattered light and when you look at the end of the glue stick you see what is left.

What absorbs more light?

The more light the object absorbs, the more heat absorbed since light is energy. If you consider it a color, black absorbs the most heat. A black object absorbs all wavelengths of light and reflects none. Objects that are white, on the other hand, reflect all wavelengths of light and therefore absorb the least heat.

What happened when the light is pointed through the mixture?

Answer: When light is shined through a true solution, the light passes cleanly through the solution, however when light is passed through a colloidal solution, the substance in the dispersed phases scatters the light in all directions, making it readily seen.

What type of mixture will not allow light to pass through?

A solution is always transparent, light passes through with no scattering from solute particles which are molecule in size. The solution is homogeneous and does not settle out. A solution cannot be filtered but can be separated using the process of distillation. A suspension is cloudy and heterogeneous.
