Electrical Heating Unit

The conversion of electrical energy to heat energy is known as electric heating. The heating system that converts the electrical energy to heat energy for various application is called electrical heating unit. Electricity is employed as the firing mechanism in electric heating systems, which transforms electric current to heat. Electric heaters have heating elements in the form of electric resistors.

What is the shortest time taken for a 100 Hz a.c. to change from zero to half its peak value? (Assuming the current is a sine wave, I correctly calculated that time to reach its peak value from zero is 2.5ms. However for the question given, 1.25ms was marked wrong and the comment "draw the waveform and think about the time in terms of the period" was left. Please help me understand this)
