Suppose an electron and a proton move at the same speed. Which particle has a longer de Broglie wavelength

Therefore, electron will have a longer de Broglie Wavelength.

Explanation:

The de Broglie wavelength is given by the following formula:

λ = h/mv

where.

λ = de Broglie wavelength

h = Plank's Constant

m = mass of the particle.

v = speed of the particle

Since, the speed of both electron and proton is same and Plank's constant is also a constant. Therefore, the de Broglie wavelength depends solely upon the mass of electron and proton, as follows:

λ ∝ 1/m

It shows that wavelength is inversely proportional to the mass of particle.

Since, the mass of electron is less than the mass of proton.

Therefore, electron will have a longer de Broglie Wavelength.

the answer is b i think

layers of the earth affect the waves and these effects are seen on instruiments such as seimometers
