Answer:
Energy decreases and wavelength gets longer.
Explanation:
The energy of a wave is given by :

Where
h is Planck's constant
f is the frequency of the wave
As frequency decreases, the energy of the wave also decreases and wavelength gets longer. Hence, the option is (d).
Protons=33 / electrons:42

Explanation:
In a nutshell, stars are mainly made of hygrogen, element 1.
over time, elements got more dense as they collided and cooled, leading to other gases, metals...
then they explode, which lead to all kinds of further complex elements.
The stuff that makes up the universe a lot of it is from exploding star stuff, and the Earth was built up upon these remains and the atoms that make up organisms even could originally be from stars.
