|
frequency & medium
|
|
|
wavelength & frequency
|
|
|
medium & wavelength
|
|
|
color & medium
|
Explanation:
Detailed explanation-1: -The speed of electromagnetic waves is about 300 million meters per second (3.0 x 108 m/s). All electromagnetic waves travel at the same speed across space, but they may differ in their wavelengths, frequencies, and energy levels. The speed of a wave is a product of its wavelength and frequency.
Detailed explanation-2: -Light of different wavelengths, or colours, travels at different speeds when they travel through any medium other than vacuum.
