Vibration- Rotation Spectroscopy of HCl and DCl Purpose: To determine the fundamental vibration frequency and bond length for H35Cl‚ H37Cl‚ D35Cl‚ and D37Cl and to compare the isotope effects to theoretically predicted values. Introduction Vibration spectroscopy is one of the most important tools for the accurate determination of molecular structure. Vibration spectroscopy also plays an important role in environmental chemistry. For example‚ the albedo of the earth’s atmosphere is controlled by the

EXPERIMENT 7 EXPERIMENT 7 EXP 7: THE FOCAL LENGTH OF A CONVEX LENS BY GRAPHICAL METHOD EXP 7: THE FOCAL LENGTH OF A CONVEX LENS BY GRAPHICAL METHOD ABSTRACT The report is about the focal length of a convex lens using the graphical method. The aim of the report is to determine the focal length of a convex lens using the graphical method. The focal length of an optical system is a measure of how strongly the system converges or diverges light. The method that was used was experimentation

time period of a pendulum. Research question: How does the length of a pendulum affect its time period? The independent variable is the length. The dependent variable is the time. Controlled variable is the mass of the pendulum bob. Formula for 1 period of oscillation of a pendulum of a certain length is T=2π √lg Where l is length and g is gravity (9.81 ms-2) T2= 4π2 lg T2= 4π2g l Hypothesis: The longer the length of the pendulum is‚ the longer the time that is needed to

The length-tension relationships represent an important part in the function of skeletal muscle. When skeletal muscle is stimulated‚ passive tissue rapidly changes into dynamic tissue which can produce force. Furthermore‚ during this process‚ the length of muscle may decrease‚ increase‚ or remain the same. Moreover‚ the amount of power a muscle can produce depends on its length‚ velocity and stimulation Powers & Howley (2015). Muscle velocity and stimulation are normally in a constant when creating

appear to diverge from it after passing through a concave lens. The focal length‚ f of a lens is the distance between the focal point and the optical centre of the lens. For a convex lens‚ the ticker the lens is at the centre‚ the shorter is the focal length of the lens. For a concave lens‚ the thinner the lens is at the centre‚ the shorter is the focal length of the lens. Objective: To determine the focal length of a convex lens. Theory From the lens formula‚ 1 = 1 + 1
