Why is light so narrow on the spectrum?
Light is narrow on the spectrum because it consists of electromagnetic waves with specific wavelengths. Each color of light corresponds to a different wavelength, resulting in the distinct colors we see in the visible spectrum. This narrow range is due to the specific interactions between photons and atoms/molecules that determine the wavelengths of light that are emitted or absorbed.
What is purpose of monochromator?
A monochromator is used to select a narrow range of wavelengths from a broader spectrum of light. It is commonly used in scientific instruments like spectrometers to analyze and study the properties of materials based on their spectral characteristics. By isolating specific wavelengths, monochromators help in achieving accurate and precise measurements in various research fields.
What a spectrograph looks like?
A spectrograph typically consists of a long, narrow slit to allow light in, a diffraction grating or prism to disperse the light into its component wavelengths, and a detector to capture and record the resulting spectrum. The final output is a graph or image showing the intensity of light at different wavelengths.
How would a light grow in pure yellow light?
A plant's growth under only yellow light would be limited because yellow light contains a narrow range of wavelengths that are not optimal for photosynthesis. Plants rely on a wider spectrum of light, including blue and red wavelengths, to drive photosynthesis effectively. Without these wavelengths, the plant's growth and development would be stunted.
What is pure spectrum?
Pure spectrum refers to a light source that emits radiation over a narrow range of wavelengths, without any additional colors or frequencies present. This can be ideal for certain scientific experiments, such as spectroscopy, where precise wavelengths of light are needed for analyzing materials. Pure spectrum sources can include lasers or specially designed filters to achieve the narrow wavelength range.
What is detected by the eyes?
The eye detects visual light, which is a quite narrow spectrum of electromagnetic wavelengths.
How does diffraction effect wavelength?
Diffraction causes light waves with different wavelengths to bend around obstacles or through narrow openings. The amount of bending depends on the wavelength of the light - shorter wavelengths bend more than longer wavelengths. This effect is particularly noticeable when light passes through a narrow slit or around small objects.
Why do we use filters in planck's constant experiment?
we use a broad source of visible wavelengths from the lamp. These were then filtered to a variety of narrow bands of wavelengths (from placing different filters in the apparatus)
What spectrum contains only specific wavelengths?
A monochromatic spectrum contains only specific wavelengths of light, typically consisting of a single pure color. This type of spectrum is characterized by a narrow band of wavelengths with little to no variation in frequency or energy.
What is a very narrow range of wavelengths in the electromagnetic spectrum that humans can see?
The visible light spectrum is the narrow range of wavelengths in the electromagnetic spectrum that humans can see, typically between 400 to 700 nanometers. Beyond this range lie ultraviolet and infrared radiation, which are invisible to the human eye.

This narrow range is due to the specific interactions between photons and atoms/molecules that determine the wavelengths of light that are emitted or absorbed.
What is the difference between monochromator and polychromator?
A monochromator is an optical device that transmits a single wavelength or narrow band of wavelengths of light, while a polychromator transmits multiple wavelengths or a broad range of wavelengths simultaneously. Monochromators are used to select specific wavelengths for experiments, while polychromators are used to analyze or measure a range of wavelengths in a single operation.
What is the purpose and function of a narrow band pass light filter?
A narrow band pass light filter is used to allow only a specific range of wavelengths of light to pass through while blocking others. Its purpose is to isolate and enhance certain colors or wavelengths of light for various applications such as photography, spectroscopy, and optical communications.
Narrow lines of colors with no light in between them are called what?
Narrow lines of colors with no light in between them are called dark lines. They are typically seen in the spectrum of light when certain wavelengths are absorbed or blocked.
Why is a photon seen as narrow bars of light instead of a rainbow of lights?
A photon is just one particle, having necessarily just one wavelength; it cannot produce a rainbow, which requires a whole range of wavelengths. The narrow bar effect is the result of the instrument used to measure a photon, which has a narrow slit through which the photon passes.
