Answer:
Part a)
Part b)
Part c)
Explanation:
Part a)
As we know that frequency = 1 MHz
speed of electromagnetic wave is same as speed of light
So the wavelength is given as
Part b)
As we know the relation between electric field and magnetic field
Part c)
Intensity of wave is given as
Pressure is defined as ratio of intensity and speed
D, the primary colors of pigments mix to make white.
Cyan, magenta and yellow don't make white, instead they make black.
Answer:
Power generated will be equal to 1054.046 watt
Explanation:
We have given mass m = 0.129 kg
Length of the rope = 3.70 m
So mass density
Amplitude A = 0.200 m
Wavelength = 0.600 m
Velocity of the wave v = 24 m/sec
So frequency
Now angular frequency will be equal to
We have to fond the generated power
Power will be equal to
So power generated will be equal to 1054.046 watt
