OPTION D is the correct answer.
Refer to the attachment for complete calculation...
#1
length of one complete wave shape is known as wavelength
#2
Frequency is defined as number of oscillations per second or number of waves passing through a point in one second.
#3
One Time period is the time to cover one complete wavelength distance by the wave
#4
relation between time period and frequency is given as

#5
Time period of simple pendulum is given as

so it depends on length of pendulum and acceleration due to gravity
#6
amplitude of the wave is the height above the axis to which particle can attain its maximum position or its maximum height on y axis is amplitude
The troposphere is the layer of the atmosphere which contacts the surface of the Earth. This layer is <span>0 to 12 km (0 to 7 miles).
