If i decrease the wavelength of an electromagnetic wave what will happen to the frequency of the wave?

This can be viewed as a decrease in the wavelength of the wave. A decrease in wavelength at a constant speed is associated with an increase in frequency since waves follow the equation v=f*λ, where λ is the wavelength and f is the frequency.

the answer would be a

find the surface area of the sphere to the nearest square unit. use a calculator.
