Number 33 apparently the answer is 4 but i have no idea why

It would help if you managed to capture the whole question and all the answer choices
in the picture. Fortunately, you caught the whole question in the picture of #32.

Tools you need in order to answer this one:
-- When the frequency of a wave goes up, the wavelength gets shorter. 
(That's why the high numbers on a radio receiver are called 'short-wave'.)
-- Photons with higher frequency carry more energy.
(That's why x-rays and gamma rays are dangerous to our delicate human tissues.)

Do you remember hearing these things in class ?

Anyway, as the frequency of the photons increases,  their
energy increases, and their wavelengths get shorter.

I hope that's one of the choices that escaped getting caught in the photo.

This is what i found on google “what happens to the bond angle when you add or remove an electron domain? the bond angle decreases as you add domains 5. can you force the atoms into new configurations by pushing atoms around? note: we can think of a bond or a lone pair of electrons as a “domain” of electrons.” i hope this you

This ain't even a question. speak english
