It depends on the length of the item you're making noise with. If you hit the lowest part of the item you get a low pitch. If you hit the top part of the item you get a high pitch.

I hypothesis that with the assumption that nights being colder and a soccer ball in front of sunlight being hot that nights would be much air condense giving the look of deflation where as sunlight could even expand the air but normally not as noticable as the cold condensing ball.

And for an experiment you could fill a balloon or ball with room temp. air and freeze it over night and then the next day expose it to sunlight for a couple of hours and compare both results

Which is the wavelength of a wave that travels at a speed of 3.0 × 10^8 m/s and has a frequency of 1.5 × 10^16 Hz?

Answer:

2 x 10^-8

Explanation:

the formula of wavelength is

the speed divided by frequency

so you have the speed given = 3.0x10^8m/s

and frequency = 1.5×10^16 Hz

so wavelength = 3.0x10^8m/s / 1.5x10^16 Hz
