Applied physics and computer application is subjects that play a crucial role in the B.Sc. Home Science curriculum for women's colleges.
Applied physics helps students understand the scientific principles behind various home science concepts such as food preservation, textile technology, and household appliances (Fan, Mixer, refrigerator, air conditioner, washing machine and electric motors). It also enables them to develop critical thinking skills and problem-solving abilities, which are essential for their future careers.
computer application helps students learn how to use various software programs to manage data, create (presentations, word documents, excel), to use social media platforms, email, and design graphics. It also helps them understand how technology can be used to improve various aspects of home science such as food processing and nutrition analysis. it is essential for home science graduates to have a good understanding of basic computer applications.
Overall, applied physics and computer application are crucial subjects that help B.Sc. Home Science students develop a strong foundation in both theoretical and practical aspects of their field. This knowledge will not only help them excel academically but also prepare them for successful careers in various industries related to home science.
