An intense emission line for a new element is observed at a wavelength of 675 nm. what is the energy of a single photon of this light? energy =

Explanation:

Where,  

h is Plank's constant having value

c is the speed of light having value

is the wavelength of the light

Given,

Thus, applying values as:

a pan containing water is placed in a positio n where it is exposed to a 10 mile per hour wind. the pan contains a uniform depth of 1.27 cm of water, is quite wide, and has a length of 2.44 m in the wind direction. the water in the pan is at a constant temperature of 15.5 °c.

the answer is 75.0%.
