Which one is correct about Wien’s law for blackbody radiation?
It gives the relationship between
the maximum wavelength and intensity
the temperature and intensity
the range of wavelength and frequency
the wavelength for its maximum intensity and temperature

Based on Wien’s law and Blackbody radiation spectrum, the Earth’s radiation curve peaks at:
right side of Sun’s peak
left side of Sun’s peak
shorter wavelength side of Sun’s peak
all of above
