What is effect of intensity of light?
What is effect of intensity of light? Intensity cannot change the cut off frequency or stopping potential. High intensity means more number of photons, so chances of hitting to electron by them increase and hence more photo electron are emitted i.e., photo current increases. Why intensity decreases as distance from the light source increases this […]
How do you calculate heat of combustion?
How do you calculate heat of combustion? The heat of combustion is calculated by multiplying the mass of the water times the specific heat of the water times the change in temperature. This entire equation is multiplied by -1, because heat of combustion is negative because heat is being lost or released. What is combustion […]
