If the wavelength of light is halved, what happens to its frequency? (2021)
Step 1: Understand that wavelength (λ) is the distance between two peaks of a wave.
Step 2: Know that frequency (f) is how many waves pass a point in one second.
Step 3: Remember the relationship: frequency (f) is inversely proportional to wavelength (λ). This means if one goes up, the other goes down.
Step 4: If the wavelength (λ) is halved, it means it is shorter.
Step 5: Since frequency (f) is inversely proportional to wavelength (λ), if λ is halved, frequency (f) must increase.
Step 6: Specifically, if the wavelength is halved, the frequency is doubled.
Wave Properties – Understanding the relationship between wavelength and frequency in wave physics, specifically that frequency is inversely proportional to wavelength.
