Microwaves which travel with the speed of light are reflected from a distant aeroplane approaching the waye source radar. It is found that when the reflected waves are beat against• the wave sradiated from the source, the beat frequency is 990 Hz. If the micro waves are 0.1 m in wavelength, what is the approaching speed of the aeroplane.

    Long range radio transmission is possible when the radio waves are reflected from the ionosphere. For this to happen the frequency of the radio waves must be in the range:

    On a particular day , the maximum frequency reflected from the ionsphere is 10 MHz . On another day , it was found to decrease to 8 MHz . Calculate the ratio of the maximum electron densities of the ionosphere on the two days .

    When a plane wave front incident on a concave mirror as shown in figure then shape of reflected wave front just after reflection :-

    In a big hall, at a distance of 120 m from a source of sound, an observer is receiving the sound waves. At the mid-point, the waves are reflected from the ceiling of height 25 m. If the observer also receives these reflected waves, then find the wavelength of sound so that constructive interference takes place between the original wave and reflected wave:

    Assertion: In a string wave, during reflection from fix boundary, the reflected wave is inverted. Reason: The force on string by clamp is in downward direction while string is pulling the clamp is upward direction.
