संकल्पना:

  • सपाट आरसा: सपाट आरसा म्हणजे सपाट (समतल) परावर्तित पृष्ठभाग असलेला आरसा.

सपाट आरशाद्वारे तयार झालेल्या प्रतिमेची वैशिष्ट्ये:

  • सपाट आरशाद्वारे तयार झालेली प्रतिमा नेहमी आभासी आणि सुलटी असते म्हणजेच प्रतिमा ही स्क्रीनवर प्रक्षेपित किंवा केंद्रित केली जाऊ शकत नाही.
  • आरशाच्या मागील प्रतिमेचे अंतर आरशासमोरील वस्तूच्या अंतराच्या समान असते.
  • तयार झालेल्या प्रतिमेचा आकार वस्तूच्या आकारासमान असतो.
  • प्रतिमा पार्श्विकतः उलटी असते, म्हणजे सपाट आरशातून पाहिल्यावर डावा हात उजवा हात असल्याचे दिसते.

  • जर एखादी वस्तू आरशाच्या दिशेने (किंवा दूर) एका विशिष्ट गतीने गतिमान असेल, तर प्रतिमा देखील त्याच गतीने आरशाकडे (किंवा दूर) सरकते.

स्पष्टीकरण:

वरील चर्चेवरून आपण असे म्हणू शकतो की, सपाट आरशाद्वारे तयार झालेली प्रतिमा नेहमीच आभासी आणि सुलटी असते. म्हणून, पर्याय 3 योग्य आहे.
