Only a fraction of the electrical energy supplied to a tungsten light bulb is converted to visible light. the rest of the energy shows up as infrared radiation (i. e., heat). a 75-w light bulb converts 15.0% of the energy supplied to it into visible light. assuming a wavelength of 550 nm, how many photons are emitted by the light bulb per second? (recall 1 w = 1 j/s)

Explanation:

It is given that,

Power of the light bulb, P = 75 W

Wavelength,

It is mentioned that light bulb converts 15.0% of the energy supplied to it into visible light. 15 % of 75 W is,

Let n is the number of photons emitted by the light bulb per second. It is given by :

Hence, this is the required solution.

the temperature and the pressure affect solubility. temperature affects by changing the properties of the solvent. the increase in pressure increases solubility, the decrease in pressure decreases solubility.
