Will a spectrum be formed if a ray of monochromatic light falls on a prism?

No, a prism won't split a laser beam into a visiblespectrum. Light from most lasers is almost monochromatic, so glass prisms bend the light without splitting it.
However, lasers are not perfect, and their spectrum is not an infinitely narrow line. The "linewidth" for a diode laser is a few megahertz, or about a billionth of a percent of the laser wavelength. So, if you use a prism to bend a laser beam, the beam will become slightly spread out, but only by about a hundred-billionth of the deflection angle.
On the other hand, certain lasers are designed to emit light of several different frequencies at the same time. The argon-ion lasers used for laser light shows are these types. If you use a prism to deflect the beam of this sort of laser, the beam will be split into two or more colors. But once split, each color behaves as an independent monochromatic laser beam.

∙ 8y agoMonochromatic light has a single wavelength hence no spectrum will be formed when it passes through prism .
When white light passes thropugh prism we get VIBGYOR i.e. seven colours of light. This happens because all the 7 colors of light have the same frequency but different wavelength

What will be the resulting spectrum if use a monochromatic light instead of sodium vapour lamp in diffraction grating?
You will observe a series of bright and dark fringes uniformly spaced, of the color of the monochromatic light used.
What happens to the spectrum if a red light shines on a prism?
red light is monochromatic light and if it shines on a prism its still red light pass through the prism, not 'rainbow' color.
Can a spectrum be formed by reflection of white light?
No, but it can be formed by refraction.
Difference between normal light and laser light ray?
white light is the full visible like spectrum. lasers are monochromatic. a single or very narrow frequency or wavelength.
What is monochromatic in physics terms?
Mono means single Chrome means colour So monochromatic means single coloured light Example: Light coming from Sodium vapour lamp ---- Monochromatic means (light) of a single frequency or, what is the same thing, of the same wavelength.
Is monochromatic light is a ultra violet light?
Monochromatic light is light of one wavelength. E.g. A red laser has one single wavelength and is therefore categorised as 'monochromatic light'. A standard light bulb emits light of many different wavelengths across the visible spectrum and therefore is not 'monochromatic light'.
What will be the resulting spectrum if use a monochromatic light instead of sodium vapour lamp in diffraction grating?
You will observe a series of bright and dark fringes uniformly spaced, of the color of the monochromatic light used.
What color is a monochromatic light?
It can be any color on the spectrum, as long as it is a pure single wavelength (mono = one) color.
Is sodium lamp monochromatic?
No, sodium lamps are not monochromatic. They emit a broad spectrum of light, with a characteristic yellow-orange color due to the dominant emission of spectral lines in the yellow region.
Why light emitted by bulb is not monochromatic?
Light bulbs aim to emulate the light emitted by the Sun, which radiates as a black body at 6000 degrees C. The light is emitted over the entire visible spectrum. Some bulbs produce monochromatic light, sodium street lights for example.
What happens to the spectrum if a red light shines on a prism?
red light is monochromatic light and if it shines on a prism its still red light pass through the prism, not 'rainbow' color.
Can a spectrum be formed by reflection of white light?
No, but it can be formed by refraction.
Difference between normal light and laser light ray?
white light is the full visible like spectrum. lasers are monochromatic. a single or very narrow frequency or wavelength.
Where does visible light fall on electromagnetic spectrum?
Visible light falls between the wavelengths of 380 nm and 760 nm in the electromagnetic spectrum.
What type of light is formed when all of the lights of the visible spectrum combine?
White light contains all the colors of the visible spectrum.
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.
What is monochromatic in physics terms?
Mono means single Chrome means colour So monochromatic means single coloured light Example: Light coming from Sodium vapour lamp ---- Monochromatic means (light) of a single frequency or, what is the same thing, of the same wavelength.
