Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFसंकल्पना:
- अपवर्तनांक (μ): निर्वातामधील प्रकाशाच्या वेग आणि माध्यमातील प्रकाशाच्या वेगाच्या गुणोत्तराला त्या माध्यमाचा अपवर्तक निर्देशांक म्हणतात.
\(\text{The refractive index of a substance/medium}=\frac{\text{Velocity of light in vacuum}}{\text{Velocity of light in the medium}}\)
म्हणून, μ = c/v
जेथे c हा निर्वातातील प्रकाशाचा वेग आहे आणि v हा माध्यमातील प्रकाशाचा वेग आहे.
गणना:
दिलेल्याप्रमाणे:
हिऱ्याचा अपवर्तनांक (µd)= 2.5
आपणास माहित आहे
निर्वातामध्ये प्रकाशाचा वेग (c) = 3 × 108 मीटर/सेकंद
हिऱ्यातील प्रकाशाचा वेग शोधण्यासाठी (v)
आता,
\(μ _d=\frac{c}{v}\\ or, \; 2.5= \frac{3 \times 10^8}{v}\\ or, \; v=\frac{3 \times 10^8}{2.5}=1.2\times 10^8 \; m/s\)
म्हणून, पर्याय 1 योग्य आहे.
