संकल्पना:

प्रकाशाचे अपस्करण:

  • प्रकाशाचे अपस्करण म्हणजे लोलकामधून जाताना पांढऱ्या प्रकाशकिरणाचे त्याच्या घटक रंगांमध्ये विभाजन होण्याची घटना.
  • अशा प्रकारे प्राप्त झालेल्या सात रंगांच्या पट्ट्याला (दृश्यमान) वर्णपट म्हणतात.
  • पांढर्‍या प्रकाशाचा अपस्करण होते कारण पांढर्‍या प्रकाशाचे रंग काचेच्या लोलकामधून वेगवेगळ्या वेगाने प्रवास करतात.

स्पष्टीकरण:

  • जेव्हा लोलकाद्वारे पांढर्‍या प्रकाशाचे अपस्करण होते, तेव्हा जांभळ्या रंगाचे  कमाल विचलन होते आणि लाल रंगाचे  किमान विचलन होते. त्यामुळे पर्याय 2 योग्य आहे.
