hello i need some help with these physics questions please exaplin the answer clearly step by step in so that i am able to understand how to do the problems thank you!

The wavelength of a longitudinal wave is the distance between A. successive compressions / K B. successive rarefactions / \\. both A and B K \\ None of the above / k The vibrations along a transverse wave move in a direction D . / along the wave perpendicular to the wave { K. both I K. neither { K. The distance between adjacent peaks in the direction of travel for a transverse wave is its frequency period wavelength O amplitudeA wave with a wavelength of 10 meters and time between crests of 2 seconds is traveling in water. What is the wave speed? ( Hint: Wave speed = frequency x wavelength ) ( Hint: Frequency = 1/Period ) O 1 m/s 2 m/s 5 m/s 10 m/sThe frequency of a particular wave is 20 Hz, its period is Relevant equations: T=1/f 0 more than 20 s O none of the above A sound wave has a frequency of 500 Hz. What is the period of vibration of the air molecules due to the sound wave? ( Hint: Period = 1/frequency ) \f\fYou see lightning strike the ground and hear thunder 3 seconds later. It is a cool day and the speed of sound is 340 m/s. How far are you from the strike? 03m 00m O 340m Q 1020m mm 10"5 nm 10 3 nm 1 nm 10' nm 10 nm 1 m 10'm Gamma rays X rays Ultraviolet Infrared Microwaves Radio waves 1024 Hz 10 2 Hz 1020 Hz 10 8 Hz 1016 Hz 1012 Hz 1010 Hz 10" Hz 10% Hz 10'Hz 102 Hz Visible light 7 X 1014 Hz 4 X 1014 Hz Which has a longer wavelength, radio waves or x-rays? Radio waves O x-rays they are the sameAll of the following are part of the EM spectrum except \\ , radio waves O gamma rays
