What are the two types of errors in measurements?
The two types of errors are: 1. Systematic Errors - Occur due to defective instruments or incorrect calibration. 2. Random Errors - Arise from unpredictable fluctuations during measurements. For more please visit here: https://www.tiwariacademy.com/ncert-solutions/class-11/physics/chapter-1/

Q.23. A concave lens of refractive index 1.5 is immersed in a medium of refractive index 1.65. What is the nature of the lens?
When a concave lens (n = 1.5) is immersed in a medium with a higher refractive index (n = 1.65), it behaves as a convex lens, as the medium bends light more strongly than the lens. For more visit here: https://www.tiwariacademy.com/ncert-solutions/class-12/physics/chapter-9/

Define dimensional formula.
The dimensional formula expresses a physical quantity in terms of the base dimensions M (mass), L (length), T (time), etc. For example, velocity's dimensional formula is [𝑀^0L^1T^-1]. For more please visit here: https://www.tiwariacademy.com/ncert-solutions/class-11/physics/chapter-1/
