| SCIENCE - FORM 2 | | The World Through Our Senses | | SENSORY ORGANS AND THEIR FUNCTIONS 1. Sensory organs are used to detect every changes in the environment. (a) Sensory organs are possessed by human and all animals. (b) Sensory organs allow the body to respond to the stimuli surroundings. Stimuli from the surroundings. Stimuli are changes that happen in the environment. (c) Sensory organs have receptors that receive the stimuli and then‚ send them as impulses to the

REFRACTION THROUGH A LENS Lens: Lens is a transparent refracting medium bounded by two curved surface which are generally spherical. Types of lens: Generally there are two types of lens: 1. Convex lens: It is a lens which is thicker at the middle and thinner at the edges. It is also called converging lens as the light rays converges on passing through it at a point. Focal length of convex lens is taken as positive. 2. Concave lens: it is a lens which is thicker at the edges and thinner at the middle

OBJECTIVE The objective of this experiment is to study refraction and reflection and also to use Snell’s law correctly to determine the optical properties and indices of refraction for a prism. DATA All data is included in an excel spreadsheet‚ attached to this write-up. Some uncertainties that see probable in the case of general human error are the basic visualization of the location of the pin‚ the measuring of the angles with a protractor‚ the possibly imprecise way to draw the reflected

Spherical Mirror :A curved mirror formed by a part of a hollow glass sphere with a reflecting surface (created by depositing silver metal) is also referred to as a spherical mirror. Concave Mirror:A concave mirror is a curved mirror with the reflecting surface on the hollow side (created by depositing silver metal on the outer curved side). Convex Mirror : A convex mirror is a curved mirror ------------------------------------------------- with the reflecting surface on the outerside
