Question

If wavelength of light us increased does speed increases or decreases

Answer 1

A decrease in wavelength at a constant speed is associated with an increase in frequency since waves follow the equation v=f*λ, where λ is the wavelength and f is the frequency. ... Thus the wavefronts reach the observer with a longer time interval between them than emitted wave.

Answer 2

A decrease in wavelength at a constantspeed is associated with an increase in frequency since waves follow the equation v=f*λ, where λ is the wavelength and f is the frequency. ... Thus the wavefronts reach the observer with a longer time interval between them than emitted wave
