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.

You have to multiply the joules/photon by Avogadro's Number, i.e., by the number of particles in a mole.

What in tarnation is a "mole" of photons ???Don't you have to know the atomic number or the molecular weight of an element or compoundin order to know the size of a mole ?Do you happen to know the atomic number or the molecular weight of a Photon ???I don't think Avogadro was talking about photons.

The number of joules to raise one gram of water by one degree Celsius is 4.2 Joules. The total number of joules needed then is 95,088 joules.

You don't, as the wavelength is totally independent of the number of photons. You could have one or a trillion different photons, each of 600nm.

There can be as little as one if it has the right energy for that wavelength, number of photons has nothing to do with wavelength. The number of photons only determines the intensity/brightness.

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.

A calorie is about 4.2 joules, therefore a kilocalorie is about 4200 joules. You can multiply by this number.

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)

1 BTU = 1 055.05585 joules so 22000 BTU = 23211228.75764 joules (approximately)

Neither. The beams of red light and green light will have the same number of Photons, as energy is only related to frequency. The number of Photons is dependent on the intensity of the light beams.

A hard beam is one that contains a greater number of high energy photons than low energy photons.A soft beam is one that contains a greater number of low energy photons that high energy photons.During the filtration of a heterogenous beam (one that contains photons with different energies), low energy photons are removed from the beam, effectively "hardening" it.

9*10^15 billion what? You cannot convert a number into joules without units. A number is meaningless w/o units.

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.

the number of photons being emitted from a light source.

Increasing the intensity of light will increase the number of photons arriving per second. Increasing intensity has no effect on photon energy.

You extract the hydrogen pronuerons after you subtract the number of posotive electrons.

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.

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.

Every second a 150 Watt bulb converts 150 Joules from electricity into heat and light. The number of Watts tells you how many Joules pass per second.

1 Watt = 1 Joule/second 1 kilowatt = 1000 Watts = 1000 Joules/second 1 hour = 60 minutes = 3600 seconds 1 kWh = 1000 (Joules/second) * 3600 (seconds) = 3,600,000 Joules = 3.6 MJoules

Power (Watts) is Joules (energy) per Second (time) so divide the number of joules by the number of seconds. 104/60 = 1.733 Watts

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.
