The average angular acceleration of the fan is
The number of revolutions after time is given by
Acceleration is assumed to be constant, so and over the 2 second interval we have
so the answer is A.
As frequency decreases , the wavelength will increase !!
frequency= speed of light ÷ wavelength
( inverse relationship )
Acceleration is measured in meters per second square.
