What does the intensity of a beam of em radiation mean?
The intensity of a beam can be measured by the power contained in a square metre cross-section of the beam. For example the Sun's light has an intensity of about 1400 watts per square metre.
What are the factors that influence the deflection of a beam?
Its width, depth, length the material that it is made from, the points of support
What is meant by the half value layer of a homogenous beam?
The half value layer of a homogenous beam is the thickness of the absorber that reduces the intensity of the beam to half the initial (starting) intensity.
If beam area decreases the intensity will?
Increase
Why laser produces Gaussian beam?
A laser produces a Gaussian beam because of the diffraction effect of the laser beam passing through an aperture. The electric field distribution of the beam follows a Gaussian shape due to the wave nature of light. This results in a beam that has a bell-shaped intensity profile with a narrower central peak and gradually decreasing intensity towards the edges.
What changes when the intensity the brightness of a light wave changes?
When the intensity of light changes, the number of photons in the beam increases. Keep in mind the beam has larger photon population, but the energy of individual photon is unchanged. The photons only increased in number.
What is inside an LED torch?
The electronic equipment that provides a good focus and beam with optimum luminous intensity can be referred to as Ledtorches.com.au. I purchased the SSR50 rechargeable torch from LED Torches recently.It delivers 1000 lumens intensity with a high beam.
How many photons are there in a beam of light?
More than 1. Describing the intensity of the beam will establish the number of photons per second striek a perpendicular surface of a given area.
What is the luminance of Streamlight flashlights?
On Amazon, there is a Streamlight flashlight, model 74301, that has five different settings and three different types of luminescence. On high, the peak beam intensity is 10,000 candela -160 lumens. On medium, the peak beam intensity is 5000 candela - 80 lumens; and on low, the peak beam intensity is 2500 candela - 40 lumens. According to the website Learning Centre, Streamlight uses gas-filled lamps that provide a high output and a more natural light.
What 3 factors will affect beam Spreading?
Angle and what are the others
How much of a 3.0cm material is needed to reduce beam of radiation to 25 percent of its original intensity?
The answer depends on the transmissivity of the material.
How is cancer treated in a technique called teletherapy?
a narrow beam of high-intensity gamma radiation is directed at cancerous tissue
