Transmission: Low to high density

Reflected pulse is inverted

Transmitted pulse shorter wavelength, same frequency

Machine generated alternative text: Transmission>Low to high density... . The reflected pulse is inverted (the denser, higher inertia medium behaves like a fixed end). . The transmitted pulse -Propagates more slowly: pulse Mass per unit g length of string -Has a shorter wavelength, but frequency is unchanged. Transmitted pulse

 

Transmission: Low to high density

Reflected pulse is not inverted

Transmitted pulse longer wavelength, same frequency

Machine generated alternative text: Transmission>High to low density... .The reflected pulse is not inverted (the less dense, lower inertia medium behaves like a free end). pulse . The transmitted pulse -Propagates at a higher speed, and -Has a longer wavelength, but the frequency is again unchanged. pulse pulse

 

Why does frequency remain constant?

When a transverse sine wave passes through two strings of different densities,
the string oscillates vertically, meaning that the left and right motion must cancel out,
the left and right motions are therefore equal, which means that their frequencies are the same
