Téama an Dáin

• Ceapaim gurb é 'tionchar an fhóin chliste' an príomhthéama sa dán 'Stadeolaíocht'.
• Úsáideann an file scéal gearr greannmhar chun teachtaireacht thábhachtach a thabhairt dúinn.
• Tá an file ag rá go mbímid ag cailleadh amach ar go leor rudaí tábhachtacha sa saol mar bímid sáite san fhón cliste.
• Cailleann an file an bus mar tá sé sáite ina fhón cliste.
• In áit ceist a chur ar dhuine, seiceálaimíd gach rud ar Google.
• Ba cheart dúinn an fón a chur i leataobh agus féachaint ar an saol atá thart orainn.
• Gan dabht, tá tionchar mór ag an bhfón cliste... (More)

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)
