Physics for IGCSE & O level - Waves And Sounds (Section 6 - No. 5)
What happens to the speed of a wave if the frequency increases?
The speed increases.
The speed decreases.
The speed remains the same.
The speed becomes zero.
คำอธิบาย
If frequency increases, and the wavelength remains the same, the speed increases (Speed = Frequency x Wavelength).
