Answer:

A and B

Explanation:

For an electromagnetic wave, the relationship between frequency and wavelength is given by:

\lambda\times\nu=c

where \lambda is wavelength

           \nu is frequency

           and c is speed of light.

From the formula we can say that frequency is inversely proportional to the wavelength as speed of light is a constant.

Hence

  • As frequency increases wavelength gets shorter.
  • As frequency decreases wavelength gets longer.

Answer:

D. A and B

Explanation

as frequency is inversely proportional to wavelength. formula for calculating wavelength is  

wavelength = wave velocity/frequency.

as wavelength is inversely proportional so increase in wavelength will cause decrease in frequency and vice versa . so A and B are the right answer.

What is the order in which electrons start filling the orbitals?
earnstyle [38]
<span>Take a look at this periodic table. You start in the left upper corner (1s) then you go to the right untill you can't go further, then you go 1 row down and start at the left again. So the order will be 1s,2s,2p,3s,3p,4s,3d,4p... etc</span>

Calcium must lose two electrons to get a full outer shell. what is the name of the group to which calcium belongs
11111nata11111 [884]
The answer to this question would be: alkaline earth metal

Alkali earth metal is the second column group of the periodic table. In this group, the element has 2 extra electrons in their outer cells. That is why most of this metal has 2+ charge.
Their neighbor is the alkali metal which was the first column of the periodic table. The name is similar so don't confused and mix them each other.
