Light

  • Refraction is the bending of light as it goes from one medium to another.
  • Laws of Refraction: (1) Incident ray, refracted ray & normal are on the same plane. (2) Sine I/Sine R is constant.
  • Refractive Index: Sine I/Sine R = 1/Sin C = Real depth/Apparent depth = c1/c2
  • Critical Angle: The angle whose angle of incidence is 90 when light goes from a denser to a rarer medium.
  • Total Internal Reflection: When light travelling from a denser to a rarer medium strikes the second medium with an angle of incidence greater than the critical angle, it is reflected... (More)

What are you being asked to do?

The marker is told to view each question as a task, which you must solve with your answer.

There are three question types used to test this: questions concerning what a written question is about, questions on the style of a written text, and questions on the style of a visual text.

If we look at the... (More)

Leaving Cert. English, Paper 1 – Part B (Composing Section): The Complete Guide

What are you being asked to do?

In the Part B/ composing sections you are being asked to do two things:

  1. Use language in one of five ways: to write either argumentatively, persuasively, informatively, narratively or aesthetically.
  2. Create a written medium aimed at someone (e. g a speech, letter to fellow students, parents). Before looking into these different ways of writing, we need to look at what the marker will be looking for in the answer regardless of what language genre you write in, that you are creating the written medium aimed at an audience asked...
