A 100. W lamp emits red light of wavelength 680 nm. How many photons can the lamp generate in 26 seconds? (1W = 1J/s)

The laser has a light with a wavelength of (8.01x10^2)nm.  Calculate the energy of this light.  Note: Your answer is assumed to be reduced to the highest power possible.

5) What is the energy (in kilojoules per mole) of ultraviolet light with a wavelength of 294 nm?

The power of a red laser (A = 630 nm) is 4.00 watts (abbreviated W, where 1W=1 J/s). How many photons per second does the laser emit? photon/s

A 753 nm krypton laser puts out 4.00 W of power with a beam 4.30 mm in diameter. The beam is pointed directly at a pinhole which has a diameter of 1.10 mm. How many photons of light will travel through the pinhole per second? Assume that the intensity of the light is equally distributed across the whole area of the beam. number of photons per second:

The energy of light photons varies with wavelength. Calculate the energy per mole of photons for each of the given colors of visible light. kJ red light, A = 727 nm mol green light, A = 537 nm E = kJ mol blue light, A = 407 nm E = kJ mol Splitting liquid water into hydrogen and oxygen requires an input of 286 kJ/mol. 286 kJ + H,O(1) → H, (g) + 02(g) Assuming a mechanism existed in which one photon of light could split one molecule of water, which color of visible light has enough energy to carry out this reaction? red green blue
