Answer:
1 Hz
Explanation:
For rope fixed on both ends the length corresponds to λ/2 (λ is wavelength)\
Thus L = λ/2
=> λ = 16 m
We know that frequency and wavelength are related as
f x λ = v where f is frequency and v is speed of the wave
thus f = v/λ
f = 16/16 =1 Hz
Answer:
No electromagnetic waves can not exists if changing magnetic field could produce electric fields but the changing electric fields could not produce magnetic fields. Electromagnetic waves are oscillating waves and they are based on this fact that the changing magnetic field produce electric field and the changing electric field produce the magnetic field. That is why these waves are known for self propagation and can even travel through vacuum. In this wave the electric field and the magnetic field lies perpendicular to each other. These waves travel with the speed of light and their example is light and other radiations coming from sun.
Answer:
Explanation:
= Refractive index of bubble = 1.33
f = Frequency of light = 
c = Speed of light = 
The wavelength of light is given by
Wavelength is also given by
m = 1 for minimum thickness
The minimum thickness is
Answer:
Both Thomson and Rutherford used charged particles in their experiments.
Explanation:
Answer:
power=400Watt
Explanation:
work done =12kJ=12×10³=12000j
time taken=30s
power=?
as we know that
power=work done/time taken
power=12000J/30s
power=400Watt
i hope this will help you :)
