A string is tied at both ends, and a standing wave is established. The lenght of the string is 2m, and it vibrates in the fundamental mode (n = 1). 1) If the speed of waves on the string is 50 m/s, calculate the wavelenght of the waves. (Express your answer in m and as an integer). 2)  If the speed of waves on the string is 50 m/s, calculate the frequency of the waves. (Express your answer to two significant figures).

Electromagnetic Waves

Electromagnetic waves are waves that consist of magnetic field and electric field components perpendicular to each other. These field components are also perpendicular to the direction of propagation of the wave.
