是的，剑桥大学本科确实有物理系。
更准确地说，本科物理专业是在剑桥大学的 Cavendish Laboratory（卡文迪许实验室） 下开设的，属于 Natural Sciences Tripos（自然科学课程体系） 的一部分。也就是说，剑桥没有一个单独叫“Physics Department”的本科项目，而是本科生通常先通过“Natural Sciences”进入学习，在前两年选修物理相关课程，然后逐渐专攻物理方向，第三、四年就基本是纯物理训练。
如果你是打算申请剑桥本科物理，一般要申请 Natural Sciences (Physical) 路线，然后在其中选择物理课程，最后可以拿到物理学位（BA in Natural Sciences, specializing in Physics）。
要不要我帮你整理一下剑桥本科物理的课程路径（比如第一年到第四年一般学些什么）？
以下 是grok:
Yes, Cambridge University has a Department of Physics (the Cavendish Laboratory), which is one of the world's leading physics research institutions. However, for undergraduate studies, there is no standalone "physics department" or dedicated physics undergraduate program. Instead, physics is taught as part of the broader Natural Sciences Tripos (a flexible, interdisciplinary degree). Students can specialize in physics after the first year, taking modules from the Department of Physics and related fields. This structure allows for a wide range of science subjects in the early years before focusing on physics.For more details on the Natural Sciences program, including physics pathways, you can explore the official Cambridge undergraduate admissions page.
