What do radio waves and microwaves have in common?
both have higher frequencies than visible light.
both have longer wavelengths than visible light.
both are located to the right of visible light on the spectrum.
both have lower radiant energy than visible light.

Both have longer wavelengths than visible light.

Both are located to the right of visible light on the spectrum.

Both have lower radiant energy than visible light.

Explanation:

If electromagnetic waves are arranged in the order of the energy from highest to lowest energy range then we will have

1). Gamma rays

2) X rays

3) Ultraviolet rays

4) Visible light

5) Infrared waves

6) Microwaves

7) Radio waves

Now as per energy range we can say that both microwaves as well as radio waves must have small energy range and longer wavelength as compare to visible light.

SO correct answers are

Both have longer wavelengths than visible light.

Both are located to the right of visible light on the spectrum.

Both have lower radiant energy than visible light.

magnitude and direction

answer: the correct answer is 1.

explanation: there are various process in which a radioactive nuclei decays:

1) alpha decay: in this process, a heavier nuclei decays into lighter nuclei by releasing alpha particle. the mass number is reduced by 4 units.

2) electron capture: in this decay process, a parent nuclei absorbs an electron and gets converted into a neutron. simply, a proton and an electron combines together to form a neutron. mass number does not change in this process.

3) gamma ray emission: it is a decay process in which an unstable nuclei gives excess energy by a spontaneous electromagnetic process. this decay releases . this process does not change the mass number.

4) positron emission: it is a type of decay process, in which a proton gets converted to neutron and an electron neutrino. this is also known as -decay. in this the mass number remains same.

from the above information, we see that only alpha-decay is producing a change in the mass number of the nucleus.
