## What causes refraction in water?

Refraction occurs when light goes through a water surface since water has a refractive index of 1.33 and air has a refractive index of about 1. This is due to the bending of light rays as they move from the water to the air.

## What color do you see when light passes into water?

When sunlight encounters a drop of water in the atmosphere it can produce a colorful rainbow because the amount that light rays are bent as they pass in and out of the raindrop depends on the wavelength (or color) of the light.

## What happens when light passes through a glass of water onto white paper?

Refraction and the Rainbow Refraction is a phenomenon that happens when a beam of white light passes through the interface between air and a denser medium, such as glass or water. Light travels more slowly in a denser medium, so it changes direction – or refracts – when it passes through the interface.

## What happens when light passes through glass?

When light hits a glass object, some of the light bounces (or reflects) off the glass. The rest of the light keeps going through the glass object, but the light is bent (or refracted) as it moves from the air to the glass. The index of refraction for the oil is very close to the index of refraction for glass.

## Why can I see through glass?

We can see through glass because light passes through it. When something is clear, like glass, visible light passes straight through it without being absorbed or reflected. Wood, on the other hand, absorbs the light in wavelengths we can see.

## Why light bends more when it passes through diamond than it does through glass?

The greater the refractive index the more the light refracts. Glass has a refractive index of 1.5, water 1.3 and diamond 2.42. This means that light will bend more when it hits a diamond than it will when it hits a piece of glass of the same shape. It is partly this that makes diamonds sparkle so much.

## Why does refraction not occur at 90 degrees?

When the refraction of light occurs, the incident light rays bend. If the incident light ray is incident at 900 degrees, this means that it is parallel to the normal and it cannot bend away or towards it. If the light ray doesn’t bend then refraction doesn’t occur.

## Did the light bend when you place your hand in front of the flashlight Why?

Answer: no, the flash light did not bend he just past my hand straight.

## Is possible to bend light?

Yes, light can bend around corners. In fact, light always bends around corners to some extent. This is a basic property of light and all other waves. The ability of light to bend around corners is also known as “diffraction”.

## What can you say about the path of the light as it travels?

Answer. Answer: The path of light is straight and the velocity of light is constant in uniform composition material such as glass. The path and the velocity of light changes when light enters another material such as air or water.

## Can light bend due to gravity?

Gravity bends light Light travels through spacetime, which can be warped and curved—so light should dip and curve in the presence of massive objects. This effect is known as gravitational lensing GLOSSARY gravitational lensingThe bending of light caused by gravity .

## Does Einstein bend light?

Einstein predicted that light should be bent by gravity, and Sir Arthur Eddington led an expedition to photograph the 1919 total eclipse of the sun. The photographs he took revealed stars whose light had passed near the sun, and their positions showed that the light had been bent exactly as Einstein had predicted.

## Can time be bent?

Also, under Einstein’s theory of general relativity, gravity can bend time. When anything that has mass sits on that piece of fabric, it causes a dimple or a bending of space-time. The bending of space-time causes objects to move on a curved path and that curvature of space is what we know as gravity.

## Can we create false gravity?

Artificial gravity can be created using a centripetal force. A centripetal force directed towards the center of the turn is required for any object to move in a circular path. In the context of a rotating space station it is the normal force provided by the spacecraft’s hull that acts as centripetal force.

## Does the past exist?

The past and future do not exist and are only concepts used to describe the real, isolated, and changing present. This conventional model presents a number of difficult philosophical problems, and seems difficult to reconcile with currently accepted scientific theories such as the theory of relativity.

## Can the future affect the past?

In the quantum world, the future affects the past: Hindsight and foresight together more accurately ‘predict’ a quantum system’s state. Summary: In the quantum world, the future predicts the past. All quantum mechanics can offer are statistical probabilities for the possible results.

## Is our future set in stone?

First developed by Albert Einstein early in the 20th century, the orthodox view holds that the passage of time is an illusion. There is no difference between the past and the future — both are set in stone.
