Aim To determine the critical angle of glass using a glass block Principle and Hypothesis The Snell’s Law of Refraction says that – At the boundary between any two given materials the ratio of the sine of the angle of incidence and the angle of refraction is constant for any particular wavelength. The refractive index is determined by the formula – R = Sin i Sin r Where i = angle of incidence of the ray of light r = angle of refraction of the ray of light The

through the slit. B. Law of reflection Angle of incidence is the angle formed by a ray incident on a surface and a perpendicular to the surface at the point of incidence. Angle of reflection is the angle between the reflected ray and the normal ray. The bean was seen and reflected from 10~40 degrees by 10 degrees interval from left and right. In this case‚ the plane of incidence is made by the incidence ray and reflection ray. The reflected ray is in

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

Good relationship can enhance our sense of identity. sharing special relationships with people is one of the most rewarding and elevating moments of our lives. We categorize ourselves in terms of other people and groups. Evolution has taught us that it is beneficial to live in tribes‚ where we can share out the work of daily survival. When asked about yourself‚ you may well describe yourself in terms of your work and family relationship. Although we defined ourselves by our membership of groups‚

‘Interpreter of Maladies’ explores how one culture adapts to living with another.’ Discuss. In Jhumpa Lahiri’s short story collection ‘Interpreter of Maladies’‚ the writer silhouetted the adaption of one culture to live within another in the form of allowing differences to exist and reaching a compromise. Lahiri drew the readers into the witness of different people battling with the obstacles they encounter. While some people like Mrs Sens‚ fell to the abysm of culture-displacement because of

potential. One’s identity is formed and influenced by the groups one belongs to. Humans are by nature sociable beings that must learn to cooperate for peaceful existence to occur but are also individual personalities who seek their own self fulfilment. Belonging to groups; family‚ social or environmental groups‚ can have immeasurable benefits. But while groups do provide one with a sense of identity‚ security and protection it can however result in sacrifices to selfhood and can entail certain inevitable

“A CRITICAL SOCIETY MAKES IT DIFFICULT FOR CHILDEREN AND TEENERGERS FROM MINORITY CULTURES AND GROUPS TO FIND A WAY TO BELONG” Good morning ladies and gentlemen Today I’d like to discuss and persuade you that a critical society makes it difficult for teenagers and children from minority cultures and groups to find a way to belong to a foreign country.

‘Our sense of self is very vulnerable to external pressures’ In everyday life‚ humans are surrounded with pressures that can influence the formation of their identity. External pressures such as the environment we live in‚ the culture we belong to and the presence of other people‚ are often uncontrollable and can have a crucial impact on our sense of self. This idea is explored in great depth in Ray Lawler’s classic Australian play‚ “The Summer of the Seventeenth Doll”‚ where it is reflected how
