Want this question answered?
Conventional sources are the same as conventional sources.
it aint6 a such thing as school
All electromagnetic energy (radio, light, X-rays, etc.) do the same.
Both torches will emit the same amount of light, if they are identical. It doesn't matter what medium you shine the light through, it will not change the energy output.
yes, exactly the same just in a different colour.
Stars give out light energy, that is they are luminous. Thus we see them for the same reason we see a lighted torch bulb.
Radio waves are a type of electromagnetic radiation similar to visible light. If there were 2 light sources with different color light you would not have any problem seeing both colors. It is the same with radio waves on different wavelengths.
Other than what? Please clarify.Common energy sources (for technological purposes) are fossil fuels (petroleum and coal), nuclear energy, as well as solar energy, wind energy, hydraulic (water) energy, and many others.
No they are NOT the same.
Visible light and radio waves are both two types of the same radiation (electromagnetic waves). The difference is that visible light has a higher frequency; a higher energy per photon; and a smaller wavelength.
torch
No because this year its red and last year the torch was blue.
