In air a light source emits a wavelength of 630nm under water what will the wavelength of light be?
The wavelength of light in water can be calculated using the formula: λ_w = λ_a / n, where λ_w is the wavelength in water, λ_a is the wavelength in air, and n is the refractive index of water (approximately 1.33). Plugging in the values, the wavelength of light in water would be around 473nm.

What term describes the purity of a wavelength?
Monochromaticity refers to the purity of a single wavelength in light or other electromagnetic radiation. A monochromatic source emits light at a single specific wavelength without any other wavelengths present.
What is 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.
What is the nature of source of light use in diffraction grating?
The source of light used in a diffraction grating is typically a monochromatic and collimated light source, such as a laser. This type of light source emits a single wavelength of light in a narrow, parallel beam which is important for producing sharp and distinct diffraction patterns.
What is the wavelength of charcoal?
Charcoal is not a source of light, so it does not have a specific wavelength associated with it. Wavelength is a property of light.
Is a traffic light a light reflector or light source?
A traffic light is a light source as it emits light to signal drivers when to stop, slow down, or go.
What is meant by polychromatic source?
A polychromatic source is a light source that emits several colors or wavelengths of light simultaneously. It is different from a monochromatic source, which emits light of a single color or wavelength. Polychromatic sources are commonly used in applications such as photography, microscopy, and lighting design.
What term describes the purity of a wavelength?
Monochromaticity refers to the purity of a single wavelength in light or other electromagnetic radiation. A monochromatic source emits light at a single specific wavelength without any other wavelengths present.
Is the light from an incandescent lamp monochromatic?
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.

A helium neon laser emits light of wavelength 633 nm Light from an argon laser has a wavelength of 515 nm Which laser emits the higher frequency light?
according to the wave theory of light,we have the relation that wavelength is inversely proportional to the frequency,therefore the electromagnetic wave with the lower wavelength will have higher frequency..
Why is the statement the color of an object depends on the wavelengths of light it absords inaccurate?
...because the colour of an object depends on the wavelength of light it reflects, or the wavelength of light it emits.
What is the wavelength of charcoal?
Charcoal is not a source of light, so it does not have a specific wavelength associated with it. Wavelength is a property of light.
Why is called as monocromatic source of light?
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.
Why primary fluor and secondary fluor are when it is a latter that emits light at the best wavelength?

How do colors tell you about the temperature of a star?
The colder a star is the longer the light waves it emits. Light wavelength is what we perceive as color.
Is a traffic light a light reflector or light source?
A traffic light is a light source as it emits light to signal drivers when to stop, slow down, or go.
