Suppose you hear a clap of thunder 13.4 s after seeing the associated lightning strike. The speed of light in air is 3.00 ✕ 108 m/s. (a) How far are you from the lightning strike? (The speed of sound waves in air is 343 m/s.) km (b) Do you need to know the value of the speed of light to answer? Yes No

There is a delay from the time someone sees a flash of lightning to the time that thunder is heard due to the time it takes for sound to travel from where the lightning struck to where you are when you hear the thunder. If you hear thunder 13.6 seconds after seeing the lightning, how far away did the lightning bolt strike? Take the speed of sound in air to be 343 m/s. Answer in metres.

A negative lightning strike occurs when a negatively charged cloud discharges ts excess electrons to the positively charged ground. If you observe a cloud-to- cloud lightning strike, what can you say about the charge on the area of the cloud struck by lightning?

Suppose that during a thunder-storm you hear a clap of thunder 6.06 seconds after you see a lightning strike. How far away are you from the lightning strike? Assume room temperature air. Assume light travels so fast that you see the lightning nearly instantaneously.

Distance from a lightning strike A general rule of thumb is that if you see lightning, there is one mile for every five seconds before the thunder is heard. Check this against the actual speed of sound Speed of sound at 20 C is approximately 343 m/s.

You may notice that when you are near an electrical transformer station, you hear a low frequency hum coming from the transformers. This is due to the 60 Hz AC electric current flowing the coils and around the core of the transformer. However, it turns out that the actual main frequency of the sound heard by the human ear is at 120 Hz. Using your knowledge of fundamental and harmonic overtones, present a possible explanation for this effect.

B. An observer in frame S sees lightning simultaneously strike two points 100 m apart.The first strike occurs at xi-50 m, yi-zi-ti-0 and the second at x2 -50 m, y2-z2 t2-0. (a) Find the coordinates of these two events in a frame S moving in the usual configuration at 0.9c along the x-axis of S. (b) How far apart are the events in S? (c) Find the difference in time between the events, as seen in S. Which event occurs...
