Find the de broglie wavelength of electrons in hydrogen’s n= 1 state, n= 4 state, andn= 10 state

The de Broglie wavelength for n = 1

The de Broglie wavelength for n = 4

The de Broglie wavelength for n = 10

Explanation:

Given that,

State of hydrogen’s atom are

n = 1,4 and 10

We need to calculate the energy for state

Using formula of energy

For , n = 1

For, n = 4

For, n = 10

We need to calculate the de Broglie wavelength of electrons in hydrogen’s atom

Using formula of wavelength

For,n =1

For, n=4

For, n=10

Hence, The de Broglie wavelength for n = 1

The de Broglie wavelength for n = 4

The de Broglie wavelength for n = 10

answer: 2×10^-2kg

explanation: density= mass per volume

vol=mass/density

converting to s.i units we have;

3÷1000kg = 0.003

1.5÷100m = 0.15

0.003/0.15 = 0.02kg
