In Same Direction But Are Of Different Frequencies

In Same Direction And Of Same Frequency

S_(1) : Sound travel faster in water than in air. S_(2) : The fundamental frequency of closed organ pipe increases if its diameter is increased. S_(3) : Beats are created by superposition of two sound waves with the same amplitude moving in same directions with slightly different frequncies.

Represent graphically by two separate diagrams in each case : (i) Two sound waves having the same amplitude but different frequencies. (ii) Two sound waves having the same frequency but different amplitudes. (iii) Two wound waves having different amplitudes and also different wavelengths.

An electric field is defined in terms of q_(0) a small positive charge. If the definition was in terms of a small negative charge of the same magnitude, then compared to the original field the newly defined electric field. (a) would point in the same direction and have the same magnitude. (b) would point in the opposite direction and have the same magnitude. (c ) would point in the same direction and have the different magnitude. (d) would point in the opposite direction and have the different magnitude.

There are two organ pipes of exactly the same length and material but of different radii. The frequencies of their fundamental notes are such that

Assertion: Two vectors are said to be like vectors if they have same direction but different magnitude. Reason: Vector quantities do not have specific direction.

In a plot of photoelectric current versus anode potential, how does (i) the saturation current vary with anode potential for incident radiations of different frequencies but same intensity? (ii) the stopping potential vary for incident radiations of different intensities but the same frequency? (iii) Photoelectric current vary of different intensities but same frequency of incident radiation? justify your answer is each case.

Two bombs of 5 kg and 10 kg are thrown from a cannon with the same velocity in the same direction,If the bombs are thrown in the same direction with different velocity, what would be the effect ?

Two sound waves of slightly different frequencies propagating in the same direction produce beats due to
