Physics in motion unit 6a the nature of waves

#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

pythagoras' theorem

square root (-5^2+9^2)

square root (25+81)

square root (106)

angle is tan^-1(9/5)

neg x, pos y
