Question

this is physics homework. I tried doing it but I don't know if it's correct.Plese correct if it wrong.

6. Deubling the frequency of a continsous wave will cause (i)he halved its wavelength to bi not change c) be doubled di be quadrupled 7. Doubling the frequesey of a a) be halved i continsoes wave will eause its velocity to change ei be doubled d) be quadrupled below shows the positon of a point an a string as a function of time as a continuous transverse wave passes through it. The wave crests are 20 m apart 8. The speed of the wave crests is a) 0 m's b) 10 m's c)20 m's 0 9. The amplitude of the wave is 0.5 mm ) 10m d) 40 m oscillat. Questions 10-11: Standing waves are created on a 2 m long string by attaching one end of the string to a fixed oscillator, as shown in the picture above. The other end is fixed to a rigid support. The oscillator creates a transverse wave and is adjuste its center d to a frequency of 20 Hz, when a standing wave is created with a single anti-node in 10. The velecity of the waves on this string is most nearly a) 3 m's b) 10 m's 11. The length of the string is doubled to 4 m without changing the tension in the string or the frequency of the oscillator. Which of the following will change as a resalt? a) the velocity of the wave will increase b) the wavelength of the wave will increase c) there will no longer be a standing wave created d) the number of anti-nodes present on the standing wave will increase

Explanation / Answer

all the answers attempted by you are correct, i had personally checked all calculations at my end,

I am not repeating the calculations
