The measure of a photon's energy?
wavelength
The measure of a photon's energy is?
E= hf = hc/r in Joules.
Which is more energetic a red photon or a blue photon?
The energy of a photon is inversely propotional to its wavelength. The wavelength of a blue photon is less than that of a red photon. That makes the blue photon more energetic. Or how about this? The energy of a photon is directly proportional to its frequency. The frequency of a blue photon is greater than that of a red photon. That makes the blue photon more energetic. The wavelength of a photon is inversely proportional to its frequency. The the longer the wavelength, the lower the frequency. The shorter the wavelength, the higher the frequency.
The is the particle that carries radiant energy?
photon
What is the mass of moving photon?
the mass of a photon is zero
Which is the most accurate test to measure body fat?
Dual energy X-ray absorptiometry, DEXA, is one of the more accurate methods of measuring body fat. Based on the principle that you can measure the density of bones by the amount of photon energy absorbed, this method measures bone mass, lean muscle mass and fat tissue mass.
What has the author Per Julin written?
Per Julin has written: 'Quantitative longitudinal photon absorptiometry in vitro on changes in enamel mineral mass' -- subject(s): Decalcification Technique, Dental enamel
The measure of a photon's energy?
wavelength
What dual x-ray is used as low exposure radiographic measurement of the hips and spine to measure bone density?
absorptiometry
What equipment is used to test for osteoporosis?
Dual-energy Xray Absorptiometry is used to measure bone density to detect Osteoporosis.
The measure of a photon's energy is?
E= hf = hc/r in Joules.
What are the risks of a bone mineral density test?
Bone mineral density testing is a relatively safe procedure. It is similar to an X-RAY or a CT scan, both which have minimal risks associated with the small amounts of radiation emitted. There are five main types of scans to test your bone density including: ultrasound, Dual Energy X-Ray Absorptiometry (DEXA), Peripheral Dual-Energy X-ray Absorptiometry (P-DEXA), Dual Photon Absorptiometry (DPA), and Quantitative Computed Tomography (QCT). As mentioned before the only risk is low level radiation, comparable to a normal X-RAY machine and are considered very safe.
What is dual x-ray absorptiometry used for?
Evaluation of bone density
Photon particles have mass but why light does not have mass?
Light is a beam that is shot out of a light source or explosion of gas and photon particles give of that beam which does have a mass but todays technology is unable to measure it.
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.
What is Dual energy x-ray absorptiometry also known as?
DEXA or DXA
How can you measure the mass of a photon?
One method is to determine the effectivity of the electromagnetic force over a distance. The electromagnetic force acts over an infinite distance and therefore the photon, the particle that mediates the electromagnetic force, is massless.
