In the Balmer series of the hydrogen atom, as the wavelength of spectral lines decreases, they appear:
In the Balmer series of the hydrogen atom, as the wavelength of spectral lines decreases, they appear:
Show Hint
In spectral series, the spacing between successive lines decreases as they approach the series limit.

- Equally spaced and equally intense.
- Further apart and stronger in intensity.
- Closer together and stronger in intensity.
- Closer together and weaker in intensity.

The Correct Option is D
Solution and Explanation
Hydrogen Spectrum and Balmer Series:
- The spectral lines in the Balmer series correspond to electronic transitions from higher energy levels to \( n = 2 \).
- As the wavelength decreases (moving towards the ultraviolet region), the lines become more closely spaced due to decreasing energy gaps.
- The intensity of the lines also decreases due to lower transition probabilities.
Thus, the correct answer is Closer together and weaker in intensity.
- The spectral lines in the Balmer series correspond to electronic transitions from higher energy levels to \( n = 2 \).
- As the wavelength decreases (moving towards the ultraviolet region), the lines become more closely spaced due to decreasing energy gaps.
- The intensity of the lines also decreases due to lower transition probabilities.
Thus, the correct answer is Closer together and weaker in intensity.

- Ankur Sachdeva did his MBA from ITB University. He decided to apply his knowledge of scientific management in the fast food restaurant chain 'Coffee Bean' set up by him. This restaurant was providing burgers, fries, shakes etc, as a part of its menu. Nowadays people are quality conscious, so he was using standardised raw materials, processes, methods, working conditions, machinery etc. The objective was to establish standards of excellence. By doing this he was not only able to reduce the cost but was also able to provide new varieties of burgers, fries and shakes leading to increased turnover. Ankur Sachdeva also believed that there was only one best method to maximise efficiency. As a result he developed best way of grilling burgers, cooking fries and preparing shakes. His main objective was to maximise the satisfaction of customers, which he was able to achieve. Not only to learn the best way of doing a job, but to perform their tasks efficiently, 'Coffee Bean' regularly invests in training and development programmes to equip employees with the necessary skill and knowledge. 'Coffee Bean' believed that efficient employees will produce more and earn more. This will ensure their greatest efficiency and prosperity for both company and workers. The above case highlights the use of Scientific principles and techniques by 'Coffee Bean'. Explain any one such principle and two techniques.

- Preeti started her own cooking channel on 'Youtube Mood Art'. As her subscribers increased, she was not in a position to manage everything on her own. She hired Rahul and Riya to help her with filming editing, lighting and content research. She granted authority to them to operate within prescribed limits. She was thus, able to use her time on high priority activities like developing new recipes and content development etc. As a result, Rahul and Riya were given opportunities to develop and exercise initiative. Preeti was now able to focus on objectives and meet the target of achieving a subscriber base of one million in six months.

- Nishi had gone to a grocery store to make routine purchases. On reaching home, as she took out a Binx tomato chips packet from the bag to give it to her son, she felt that it was underweight. She checked its weight on the kitchen weighing scale and found that it weighed 60 grams, whereas the label on the packet mentioned the weight as 100 grams. She approached the manufacturer and complained. The manufacturer offered her a gift hamper and requested her not to disclose the issue to anyone. Nishi refused to accept the gift hamper and took the issue to a redressal agency.
