Here's why:
* Wave speed: The speed of a wave (like light or sound) is constant in a given medium.
* Relationship: The speed of a wave is determined by the product of its frequency and wavelength:
* Speed = Frequency x Wavelength
* Inverse Proportionality: Since the speed is constant, if frequency increases, the wavelength must decrease to keep the product constant.
Example:
* High frequency (blue light): Blue light has a high frequency and a short wavelength.
* Low frequency (red light): Red light has a low frequency and a long wavelength.
Key takeaway: Frequency and wavelength are linked by a fundamental relationship, and an increase in one always corresponds to a decrease in the other.
