Velocity, Frequency, and Wavelength
Help Questions
SAT Subject Test in Physics › Velocity, Frequency, and Wavelength
Questions 1 - 2
1
What best describes how a wave is affected when it travels from one medium to another medium?
The wave speed changed, but the frequency remains the same
The frequency changes, but the speed remains the same
Both speed and frequency change
Neither speed not frequency change
The wavelength does not change
Explanation
It is a property of waves that the frequency remains constant and speed changes as it passes from one medium to another.
2
What is the wavelength of a 
Explanation
The relationship between wavelength and velocity is given by the equation;
The question gives us the velocity of the wave and its frequency. Using these values, we can solve for the wavelength.
