1. as the wavelength decreases, the frequency

The frequency will increase

Explanation:

Wavelength and frequency are inversely related such that waves with longer wavelength tend to have lower frequency and those with shorter wavelength have higher frequency. For example, gamma rays have a shorter wavelength but high frequency while radio waves have longer wavelength but have a low frequency.The product of wavelength and frequency gives the speed of the wave. Velocity = frequency × wavelengthWavelength is measured in meters while frequency is measured in Hertz.
