No! Polychromic.
IF it were then there would be no colors (or one color that you would see as white).
No, a sodium lamp is not a monochromatic lamp. It emits light in a narrow range of wavelengths, primarily the yellow-orange region of the spectrum, but it is not strictly monochromatic as it produces a broader spectrum of light compared to a true monochromatic source.
A monochromatic source is a source of light of a discrete wavelength. White light is a mixture photons with wavlengths from 390 to 750 nm (what the human eye can detect). The monochrmatic light will have a specific wavelength. For example all photons have wavelength 200 nm.
No, an incandescent bulb i.e. a bulb that emits light by the generation of heat, emits white light and is therefore not monochromatic. For a source to be monochromatic, the light emitted must be of a single wavelength.
No, mercury lamps emit light of multiple wavelengths, not just one specific wavelength, making them non-monochromatic sources of light.
The Sun light is not monochromatic.
Mercury lamps are not strictly monochromatic sources. They emit light at multiple wavelengths across the visible spectrum and also in ultraviolet ranges. While they may emit some predominant wavelengths, they are not considered fully monochromatic like lasers.
There could be, in principle, if the light source were monochromatic. But since the source is virtually always the sun or the moon, the bow displays all the colors that are in sunlight. This would be a fascinating experiment to set up if you ever have the chance. What you need is a big open inside space, like a large garage or warehouse. With the space otherwise dark, fire up a bright monochromatic spotlight at one end, stand in the middle with you r back to the light, and release a water spray into the air in front of you. You should see a 42-degree arc, or bow, of only the color of the spot light.
I am monochromatic! =D
No exactly the contrary, white light is made up of light of all the colours of the rainbow. And you need to take that literally. The rainbow has these colours because rain acts as a prism and breaks the white light of the sun apart in the colours it is made up of. Because monochromatic means 'of one and the same colour', white light is not monochromatic. LASER light is always monochromatic: all particles have exactly the same wavelength (colour)
the sun is our source of heat
No, sunlight is not monochromatic light. It is composed of a wide range of wavelengths that make up the visible spectrum, from violet to red. This gives sunlight its characteristic white color when combined.
Mono chromatic light is emitted by a laser source or by a red Light Emitting Diode. These sources emit a single wavelength of light around 550 nanoMetres. White light from the sun for example is a mixture of many wavelengths mixed together from red to violet to form white light.
