FE1002 PHYSIC 2 Tutorial 1– [optic] 2007/2008 Semester 2 FE1002 Physic 2 Tutorial 1 – Optic QUESTION 1: light with a wavelength of 700nm is incident on the face of a fused quartz prism (n = 1.46 at 700nm)at an angle of 75˚ (with respect to the normal to the surface). The apex angle of the prism is 60.0˚. Calculate the a) b) c) d) angle of refraction at this first interface angle of incident at this second interface angle of refraction at the second interface and angle between the incident and

CHAPTER – 10 LIGHT-REFLECTION & REFRACTION Light is a form of energy‚ which enable us to see the object. In this chapter we will study the phenomena of reflection and refraction using the property of light i.e. straight line propagation (Light wave travel from one point to another‚ along a straight line). Reflection of Light When the light is allowed to fall on highly polished surface‚ such as mirror‚ most of the light gets reflected. normal Laws of Reflection 1. 2. The angle

Determine the concentration of a solute in a solution by comparing the solution’s refractive index to a standard curve. To know about refractive index measurement first of all we know something about refractive index. What is refractive index? In optics the refractive index or index of refraction n of a substance (optical medium) is a dimensionless number that describes how light‚ or any other radiation‚ propagates through that medium. It is defined as ‚ Where‚ where c is the speed of light in vacuum

incident ray are on the opposite sides of the normal. These three laws can all be derived from the reflection equation. Real image – In optics‚ a real image is a representation of an object (source) in which the perceived location is actually a point of convergence of the rays of light that make up the image. Virtual image - In optics‚ a virtual image is an image in which the outgoing rays from a point on the object always diverge. It will appear to converge in or behind the optical

PLANE AND SPHERICAL MIRRORS Velorie D. Baquiran‚ Phy13L/A3 veldbaquiran@gmail.com Abstract The main theme or idea for this study circles around optics‚ more particularly on the device such as the mirror. Since light has a dual nature‚ it can travel both like a particle and like that of a wave. As the light travels from a person’s eyes‚ images can be form as it is reflected by the mirror. Properties such as reflection‚ refraction‚ interference and diffraction is identified in this study. Mirrors

8th physics light reflection refraction eyes defect and dispersion The ray of light which falls on the mirror surface is called incident ray. The point at which the incident ray strikes the mirror is called the point of incidence. The ray of light which is sent back by the mirror is called the reflected ray. The ‘normal’ is a line drawn at right angles to the mirror surface at the point of incidence. The angle between incident ray and normal is called the angle of incidence. The angle between
