The wavelength of the visible range of the electromagnetic spectrum lies between .
Further Explanation:
The Electromagnetic spectrum is the complete range of the electromagnetic radiation which expresses all the radiation starting from the Gamma rays to the radio waves. The electromagnetic spectrum is the detailed spectrum that explains all the electromagnetic radiations.
The electromagnetic radiations are the transverse waves which do not require any medium for their propagation. The electromagnetic waves can easily travel through space. All the electromagnetic radiations travel at the speed of light.
The different radiations in the electromagnetic spectrum are as follows:
The wavelength and the frequency ranges for the different electromagnetic radiations is as shown in figure attached.
Therefore, the wavelength of the visible range of the light in the electromagnetic spectrum is .

Explanation:
Visible light is a very part of electromagnetic spectrum. We can see the visible region of the electromagnetic spectrum.
The frequency and the wavelength has an inverse relationship.
For example, the red light has large wavelength and low frequency. Violet has a short wavelength and higher frequency.
The frequency range of visible region is from 400 nm to 700 nm.
nebular, i did it and its correct
Answer : The atomic symbol represent an isotope that undergoes radioactive decay to produce Pb-206 can be, Polonium (Po).
Explanation :
Alpha decay : In this process, the alpha particles is emitted when a heavier nuclei decays into lighter nuclei. The alpha particle released has a charge of +2 units.
The general representation of alpha decay,
The balanced nuclear reaction for alpha decay of polonium-210,
Hence, the atomic symbol represent an isotope that undergoes radioactive decay to produce Pb-206 can be, Polonium (Po).
Answer:
A) 238/92 U
Explanation:
Solar, wind, and geothermal energy sources are all renewable. They derive their energy from natural processes that replenish themselves over time.
There are a few things that are true about solar, wind, and geothermal energy.
Renewable energy sources include solar, wind, and geothermal power. They get their energy from natural processes that grow back eventually. Solar energy comes from the sun, wind energy comes from the movement of air, and geothermal energy comes from heat inside the Earth.
They are all environmentally friendly which means that it doesn't harm the environment. Solar, wind, and geothermal energy sources are better for the environment than fossil fuels. They release very little greenhouse gases when they are being used, which helps to prevent climate change and make the air cleaner.

The distance of the image observed by th girl is 2.77 cm.
The focal length of the lens is calculated as follows;
F = R/2
where;
R = 9 cm/2 = 4.5 cm
F = R/2
F = 4.5/2
F = 2.25 cm
The distance of the image observed by th girl is caculated as follows;
1/f = 1/v + 1/u
1/v = 1/f - 1/u
1/v = 1/2.25 - 1/12
1/v = 0.3611
v = 2.77 cm
Thus, the distance of the image observed by th girl is 2.77 cm.
