The Lyman series consists of ultraviolet spectral lines in the hydrogen atom. The wavelengths of the Lyman series range from approximately 91 nm to 122 nm. These wavelengths correspond to transitions of electrons in hydrogen atoms from higher energy levels to the ground state. The Lyman series is named after its discoverer, Theodore Lyman. **

The main difference between the Balmer and Lyman series is the energy levels involved in the transitions. The Balmer series involves transitions of electrons from higher energy levels to the second energy level (n=2), resulting in the emission of visible light. On the other hand, the Lyman series involves transitions of electrons from higher energy levels to the first energy level (n=1), resulting in the emission of ultraviolet light. Additionally, the Balmer series is the second line series in the hydrogen spectrum, while the Lyman series is the first line series. **

It is unlikely that Putin will simply give up on Lyman, as it is currently under the control of the self-proclaimed Donetsk People's Republic, which is supported by Russia. The annexation of Crimea by Russia in 2014 set a precedent for their willingness to use military force to assert control over territories they consider to be historically or strategically important. Therefore, it is possible that Putin may continue to support the Donetsk People's Republic's claim to Lyman. **

Social engagement refers to the interaction and participation of individuals within a community or society. It involves actively connecting with others, contributing to the well-being of the community, and being involved in social activities and causes. Social engagement can take many forms, such as volunteering, participating in community events, and advocating for social issues. It is an important aspect of building strong and supportive communities and fostering a sense of belonging and connection among individuals. **

Choosing between an internship and social engagement depends on your goals and priorities. If you are looking to gain professional experience and build your resume, an internship may be the better option. However, if you are passionate about making a difference in your community and want to contribute to social causes, then social engagement could be more fulfilling. Ultimately, it's important to consider what will benefit you the most in the long run and align with your values and interests. **

Yes, social engagement can be rewarded in various ways. For example, individuals can receive recognition and praise from their peers or community for their active participation and contributions. Additionally, some organizations or platforms may offer incentives or rewards for engaging in social activities, such as discounts, perks, or exclusive access to events. Ultimately, the act of engaging socially can lead to personal fulfillment, a sense of belonging, and the opportunity to build meaningful connections, which can be considered valuable rewards in themselves. **

Social engagement refers to any interaction or communication with others, both online and offline, that involves sharing ideas, opinions, or experiences. This can include activities such as participating in conversations, attending events, volunteering, or collaborating on projects. Social engagement is about building connections, fostering relationships, and contributing to the community in meaningful ways. It can take many forms and is essential for promoting a sense of belonging, support, and mutual understanding among individuals. **

Social housing promotion is not synonymous with social housing. Social housing promotion refers to the efforts and initiatives aimed at increasing the availability and accessibility of social housing, such as through government policies, funding, and advocacy. On the other hand, social housing specifically refers to the actual provision of affordable and secure housing for low-income and vulnerable individuals and families. While social housing promotion is important for addressing housing inequality, it is not the same as the physical provision of social housing units. **
