4.) The absorption line with the lowest energy. 

5.) The emission line with the highest frequency. 

6.) The line corresponding to the ionization energy of hydrogen.

Solutions

Expert Solution

Emission occur when electron moves from higher energy state to lower energy state.

C, D and E are emission.

Absorption occur when electron moves from lower energy state to higher energy state.

A and B are Absorption.

1)

C, D and E are emission.

D has largest energy and hence the wavelength would be shortest because Energy and wavelength are inversely proportional

Answer: D

2)

A and B are absorption.

B has smallest energy and hence wavelength will be longest because Energy and wavelength are inversely proportional

Answer: B

3)

C, D and E are emission.

D has largest energy.

Answer: D

4)

A and B are absorption.

B has smallest energy

Answer: B

5)

C, D and E are emission.

D has largest energy and hence the frequency would be highest because Energy and frequency are directly proportional

Answer: D

6)

In ionisation energy, electron moves from n=1 to n=infinity.

This is shown by line A

Answer: A
