Given the wavelength of the photons from above, 3000 nm you just calculate how many joules each photon has and divide that into 100 joules per second.

How many joules are in 55.2 calories?
A calorie is about 4.2 joules, therefore a kilocalorie is about 4200 joules. You can multiply by this number.
Light intensity is?
Light is composed of quanta called photons. The more photons, the greater the intensity. To see the slightest flicker of green light (the color to which our eyes are most sensitive), the minimum number of photons is six.
How is intensity of light related to photons?
Increasing the intensity of light will increase the number of photons arriving per second. Increasing intensity has no effect on photon energy.
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.
How much power does it take to do 104j of work in 60 seconds?
Power (Watts) is Joules (energy) per Second (time) so divide the number of joules by the number of seconds. 104/60 = 1.733 Watts
How do you calculate energy per mole of photons if you know joules per photon?
You have to multiply the joules/photon by Avogadro's Number, i.e., by the number of particles in a mole.
How do you you convert cal to joules?
1 calorie = 4.1858 joules 1 joule = 0.2389029576186153 calories As an example, convert 5 calories to joules. 1 calorie = 4.1858 joules, therefore 5 calories = 4.1858 x 5 joules = 20.929 joules. So when converting calories to joules, multiply the number of calories by 4.1858 to give you the number of joules.
How many joules are in 55.2 calories?
A calorie is about 4.2 joules, therefore a kilocalorie is about 4200 joules. You can multiply by this number.
What is the number of joules in 22000 british thermal units?
1 BTU = 1 055.05585 joules so 22000 BTU = 23211228.75764 joules (approximately)
How many joules are there in 135 calories?
148 calories is 619.6 joules. Since one calorie = 4.18 joules then you multiply that number by 148 and you get 618.64 joules (619 rounded)
What is 9000000000000000 billion in joules?
9*10^15 billion what? You cannot convert a number into joules without units. A number is meaningless w/o units.
How many joules are in 5.2 Calories?
162 calories is 678.2616 joules. For most purposes you don't need such accuracy, remember one calorie = 4.2 Joules. This is called the mechanical equivalent of heat, and is a useful number to memorize.
Light intensity is?
Light is composed of quanta called photons. The more photons, the greater the intensity. To see the slightest flicker of green light (the color to which our eyes are most sensitive), the minimum number of photons is six.
How is intensity of light related to photons?
Increasing the intensity of light will increase the number of photons arriving per second. Increasing intensity has no effect on photon energy.
How do you deflect photons?
You extract the hydrogen pronuerons after you subtract the number of posotive electrons.
When 20 grams of water is cooled from 20 C to 10 C the number of joules of heat released is?
200 calories, or approx. 47.84 joules
How many photons in the human cell?
The size of the human cells vary widely. The number of molecules will also vary. You have to apply the equation of Albert Einstein. That is E = m*c squared. The number of photons will be astonishingly high.
