Physics · Waves and Oscillations
निम्नलिखित तरंग फलनों में से कौन सा गणितीय रूप से एक मान्य, गैर-विक्षेपी (non-dispersive) गतिमान तरंग (traveling wave) का वर्णन करता है? (यहाँ, A0, B0, a, और b उपयुक्त धनात्मक नियतांक हैं)
- 1ψ(x, t) = A0 e(ax + bt)2
- 2ψ(x, t) = A0 / [B0(x - t)2 + 1]✓
- 3ψ(x, t) = A0 sin(ax2 + bt2)
- 4ψ(x, t) = A0(x + t)2
सही उत्तर देखें
ψ(x, t) = A0 / [B0(x - t)2 + 1]
