When it comes to wave behavior, there are parameters called wavelength and frequency. These two are related by speed of the radiowave. Radiowaves are electromagnetic waves which travels as fast as light. The wavelength is the distance while frequency is the reciprocal of time. When you multiply them both, you get the electromagnetic wave's speed. The equation is c = wavelength*frequency, where c is the speed of light equal to 3 x 10^8 m/s.
3 x10^8 m/s = wavelength/104.9 x 10^6 Hz (Hertz is 1/s)
wavelength = 2.86 meters
Answer:
towards right
towards left
Explanation:
= Mass of skater = 56 kg
= Mass of ball = 5 kg
v = Final velocity of ball = 7 m/s
u = Initial velocity of ball = 0
s = Distance the ball moved in the hand of the skater = 1 m
Moving left is considered and moving right is considered positive.
From kinematic equations of motion we have

So, the ball will move towards right with a magnitude of acceleration
.
The force on the ball will be

The force on the ball is 
The reaction force on the skater will be equal to the force on the ball but will have opposite direction.

So, the skater will move towards left with a magnitude of acceleration
