A sort of electricity is a light bulb or a phone / computer charger. plants food water. the sun and rain . that’s what i’m guessing!
Answer:
The wavelength of light is 
Explanation:
Given that,
Angle = 13.1°
Number of slits = 5000
We need to calculate the wavelength of light
Diffraction of first order is defined as,
.....(I)
The separation of the slits



Now put the value in equation (I)

Here, n = 1

Hence, The wavelength of light is 
C. since the the heat from the heater is going to the child in <u>waves</u>, it’s<u> radiating </u>
