Different colors of light travel at slightly different speeds in the material of the prism. This causes a refraction that spreads apart the colors.
Yes, water vapor can act like a prism. A rainbow is caused by raindrops, not by vapor. When light enters a raindrop at an angle to its surface, different colors refract at different angles as in a prism. A reflection occurs at the far side of the drop, and more refraction occurs as the light exits the drop, to be seen by your eye. Multiple reflections inside the drop are the cause of multiple ("double", even "triple") rainbows.
No, sodium lamps emit monochromatic light, which is not suitable for finding the dispersive power of a prism. To determine the dispersive power of a prism, you need light that contains multiple wavelengths. White light, such as from a sunlight or incandescent lamp, is typically used for this purpose.
Rainbows are formed due to the refraction, reflection, and dispersion of sunlight through raindrops in the atmosphere. Each raindrop acts as a tiny prism that separates the sunlight into its various colors, creating the vibrant arc of colors that we see in a rainbow.
Clouds reflect sunlight back to space due to their high albedo, which is the measure of how much sunlight a surface or object reflects. The water droplets or ice crystals in clouds scatter and reflect sunlight, which reduces the amount of solar radiation that reaches the Earth's surface. This reflection plays a role in regulating the Earth's energy balance and helps cool the planet.
This probably means you are on a hallucinogenic drug, because that's impossible. Sunlight entering the house is being refracted through a piece of glass, such as a vase, which is acting as a prism and thus causing a rainbow effect. There is no significance or meaning to such a phenomenon.
A prism can break up sunlight into different colors through the process of dispersion. When sunlight enters a prism, it is refracted at different angles depending on the wavelength of each color in the visible spectrum. This separation of colors creates a rainbow effect, with each color appearing at a different position as it exits the prism.
A prism and a diffraction grating are two objects that can break light into different colors by refracting and dispersing the light, causing it to separate into its component wavelengths.
The squall may have passed you but the rain is still falling elsewhere. If sunlight passes through the rain, you will see a rainbow as the water droplets work as a prism and split the sunlight into it's component colours.
Scientists use a prism or a diffraction grating to break up the sun's light into a spectrum. These tools can separate light into its component colors, allowing scientists to study the different wavelengths present in sunlight.
A clear glass prism is used to separate sunlight into rainbow colours.
A prism breaks sunlight into its component colors, revealing the phenomenon of dispersion. This occurs because different colors of light have different wavelengths and are bent by different amounts as they pass through the prism, resulting in the separation of the colors.
The violet (higher frequency) light.
The white light from a rainbow is a result of sunlight being dispersed and refracted by water droplets in the atmosphere. Each water droplet acts like a prism, breaking down sunlight into its component colors, and when the light is reflected and refracted multiple times within the droplet, we see the colors of the rainbow.
The discovery that light is made up of seven colors was credited to Sir Isaac Newton. He demonstrated this by passing sunlight through a prism and observing the separation of the light into its component colors, creating a rainbow spectrum.
When sunlight passes through raindrops, the rain drops act like a glass prism. The sunlight is split into the rainbow colours in the sky, and a rainbow appears.
The splitting of light into its component colors by a prism is known as dispersion. When white light passes through a prism, different colors of light are refracted at slightly different angles due to their different wavelengths, causing them to separate and form a spectrum of colors.
The reflection comes through the prism and different colors are different wavelength of sunlight from violet to red in the order of violet, indigo, blue, green, yellow, orange and red.
