Environmental science enlightens us on how to conserve our environment in the face of increasing human population growth and anthropogenic activities that degrade natural resources and ecosystems.
Explanation:
The scope of environmental studies is very wide and it deals with many areas like:
(i) Conservation of natural resources,
(ii) ecological aspects,
(iii) pollution of the surrounding natural resources,
(iv) controlling the pollution,
(v) social issues connected to it, and
(vi) impacts of human population on the environment.
Researchers from the TU Delft and AMOLF have built an efficient and stable photo-electrode that absorbs light and directly decomposes water into hydrogen and oxygen. Silicon wafers are used for the light-absorbing material, so that the system is cheap as well.
Answer:
The answer to your question is given below
Explanation:
From the question given above, we can see that the wave with a higher frequency has a shorter wavelength while that with a lower frequency has a longer wavelength. This is so because the frequency and wavelength of a wave has inverse relationship. This can further be explained by using the following formula:
Velocity = wavelength x frequency
Divide both side by wavelength
Frequency = Velocity /wavelength
Keeping the velocity constant, we have:
Frequency ∝ 1 / wavelength
From the above illustration, we can see clearly that the frequency and wavelength are in inverse relationship. This implies that the higher the frequency, the shorter the wavelength and the shorter the frequency, the higher the wavelength.
I believe the answer is C
