Why is a laser beam so concentrated?
it is highly monochromatic
What is monochromatic wave?
it does not spread. it is the property of laser beam
What will increase the effective energy of the xray beam?
increasing its frequency
What does a laser produce?
A laser is a device to produce an intense monochromatic beam of coherent light.
Total filtration for an xray beam is 2.5mm of lead or aluminum?
Aluminium
How is a light beam different to a laser beam?
Compared to regular light, a laser beam: * Is monochromatic. All the photons have the same frequency, and thus the same energy. * All the photons have the same phase.
Determine the energy of a single photon in a monochromatic beam of light of wavelength 625 nm?
1.99 eV
How can you tell the difference between a laser and a beam of white light?
A beam of white light is white. A laser is not; it's monochromatic (one specific frequency of light, therefore colored and not white).
What are advantages of rotating crystal?
In the rotating crystal method, a single crystal is mounted with an axis normal to a monochromatic x-ray beam.
Why a laser beam cannot be dispersed by passing it through a glass prism?
The laser beam is a highly monochromatic source of light. It consists of only one wavelength and hence does not get dispersed by using a glass prism.
Why is a laser capable of burning things?
A laser is capable of burning things because of the way they work. A laser by definition generates an intense beam of monochromatic light. This monochromatic light is actually electromagnetic radiation which because of its intensity causes things to burn.
What is the advantage of monochromatic light?
This solution iswhere source versatility is important. You can change condensers easily and have a wide selection of secondary focusing lenses to match any monochromator. The collimated beam path gives flexibility in where to locate the hardware. Accessories are available for pre filtering or spatial manipulation of the beam from the lamp housing. In the IR, where glass lenses do not transmit, an IR element is used with an reflector. best for applications
