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.

To find the number of photons being radiated per second, you need to calculate the energy of each photon first. Since the light bulb emits 100 watts (100 joules per second), and each photon has an energy of about 4.86 x 10^-19 joules for visible light, you can divide the total energy emitted per second by the energy of each photon to find the number of photons emitted.

What is the numbers of photons of light with a wavelength of 4000 pm that provide 1 j of energy?
To calculate the number of photons, you can use the formula E = n * h * c / λ, where E is the energy (in Joules), n is the number of photons, h is Planck's constant, c is the speed of light, and λ is the wavelength. First, convert the wavelength to meters (4000 pm = 4 x 10^-9 m) and rearrange the equation to solve for n. Then, plug in the values for h, c, E, and λ to calculate the number of photons.
What is the correct conversion between joules and kilojules?
To convert joules to kilojoules, divide the number of joules by 1000. For example, 1 kilojoule = 1000 joules, 5000 joules = 5 kilojoules.
How many joules are in 55.2 calories?
There are approximately 231 joules in 55.2 calories.
What is the energy of a mole of photons of red light with a wavelength of 632nm?
The energy of a photon can be calculated using the formula E = hc/λ, where h is Planck's constant, c is the speed of light, and λ is the wavelength of light. Plugging in the values, we find that the energy of a single photon of red light with a wavelength of 632nm is approximately 3.1 x 10^-19 Joules. To find the energy of a mole of these photons, you simply multiply this value by Avogadro's number (6.022 x 10^23) to get approximately 1.9 x 10^5 Joules.
Convert joules to kwh?
To convert Joules to kilowatt-hours (kWh), divide the number of Joules by 3,600,000 (the number of Joules in a kWh). For example, to convert 1,000,000 Joules to kWh, you would divide 1,000,000 by 3,600,000 to get approximately 0.278 kWh.
How do you calculate energy per mole of photons if you know joules per photon?
To calculate the energy per mole of photons from the energy per photon, you need to multiply the energy per photon by Avogadro's number (6.022 x 10^23) to account for the number of photons in a mole. The formula is: Energy per mole of photons = Energy per photon x Avogadro's number.
How many photons are in a 1.00 mJ burst of this radiation?
To calculate the number of photons in a 1.00 mJ burst of radiation, you need to know the energy of each photon. If we assume the radiation consists of photons with an energy of 1 eV, then you can calculate the number of photons using the equation: Number of photons = Energy of burst / Energy of each photon Plugging in the values, you would have: Number of photons = 0.001 J / 1 eV
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.

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)
How many photons are there in a beam of light?
The number of photons in a beam of light depends on the intensity and energy of the light. In general, there can be trillions to quadrillions of photons in a beam of visible light.
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.
