Show Hint
- P–3, Q–2, R–4, S–1
- P–4, Q–2, R–1, S–3
- P–2, Q–4, R–1, S–3
- P–1, Q–4, R–3, S–2
The Correct Option is B
Solution and Explanation
RISAT-1 operates in the C-BAND \( \Rightarrow \) Q–2
TERRASAR operates in the X-BAND \( \Rightarrow \) R–1
ALOS PALSAR operates in the L-BAND \( \Rightarrow \) S–3
So, the correct mapping is:
P–4, Q–2, R–1, S–3
Top Questions on Waves
- What is the wavelength of a sound wave with a frequency of \( 500 \, \text{Hz} \) in air? (Take the speed of sound in air as \( 340 \, \text{m/s} \))
- The amplitude and phase of the wave when two travelling waves given as $ y_1(x, t) = 4 \sin(\omega t - kx) $ and $ y_2(x, t) = 2 \sin\left(\omega t - kx + \frac{2\pi}{3}\right) $ are superimposed.
- Displacement of a wave is expressed as $$ x(t) = 5 \cos \left( 628t + \frac{\pi}{2} \right) \, \text{m}. $$ The wavelength of the wave when its velocity is 300 m/s is:
- The equation of a wave travelling on a string is $ y = \sin[20\pi x + 10\pi t] $, where x and t are distance and time in SI units. The minimum distance between two points having the same oscillating speed is :
- A light wave is propagating with plane wave fronts of the type \( x + y + z = \text{constant} \). The angle made by the direction of wave propagation with the \( x \)-axis is:
