Question

For the wave shown in figure, the wavelength of the wave is :

Answer 1

see there are 5 parts formed

therefore 40/5 give us length of each part that is 8cm

now two parts make on wavelength so 8*2= 16 cm

16 cm is the wavelength

Answer 2

Waves are 5 in number .....

and X is 40 cm......

Therefore, 40/5------>8cm.....

So now wavelength is equal to (2 ×wave)

So, wavelength is 2×8 = 16 cm
