Ответ:
Q = m * c * (T_f - T_),
where Q is the heat transferred to the water, m is the mass of the water, c is the specific heat capacity of water, and T_f and T_i are your final and initial temperatures, respectively. Now, you know that the final temperature is 100 degrees Celcius, because that is the temperature at which water boils. Rearranging the formula so that it gives you the initial temperature, you get:
T_f - Q/(m*c) = T_i
Putting in the numbers, we get:
T_i = 41.8 degrees Celcius

Explanation :
When a ray of light passes through the narrow opening then the light diffracts. The process is known as the diffraction of light.
By examining a wave's pattern after it interacts with a barrier or gap, measurements can be made to better understand diffraction wave phenomena.
After diffracting the light forms a pattern consisting of dark and bright bands.
Hence, the question could be " How diffraction of wave occurs? Explain ".
