Calculate the 4th harmonic wavelength of a a) trumpet that has a tube length of 1.20m. b) Trombone that has a tube length of 2.75m and produces a fundamental frequency of 33Hz. Calculate the 1st harmonic wavelength assuming speed of sound is 344m/s Could you please show working out :)

The title basically says it all. But i was wondering why people use green glass to build a glass house for plants instead of normal transparent glass? And what does it have to do with filters, reflection and absorption? Also could you please give website addresses? Thankyou in advance.
