Answer:
Q = 525 J
Explanation:
Given that,
Mass, m = 10 grams
The change in temperature, 
The specific heat of the substance is 3.5 J/g °C
We need to find the amount of heat released in the process. It can be given by the formula as follow :

Hence, 525 J of heat is released.
Answer:
Wavelength, 
Explanation:
Given that,
Frequency, 
We need to find the wavelength of a photon of light. The relation between frequency and wavelength is as follows :

So, the wavelength of the light is
.
