Why is water clarity an important measure of water quality?

1 answer:

8 0

Water clarity is important in water habitats. The amount of sunlight that reaches underwater plants depends on water clarity. The plants will die if they cannot get enough sunlight, and we need the water to be clean and clear so the sunlight reaches the plants. Hope that helps :)

If the wavelength of purple light is 400 x 10^-9 m, what is the frequency?

FromTheMoon [43]

The frequency : a) 7.5 x 10¹⁴ /s

<h3>Further explanation</h3>

Radiation energy is absorbed by photons

The energy in one photon can be formulated as

$\large{\boxed{\bold{E\:=\:h\:.\:f}}}$

Where

h = Planck's constant (6,626.10⁻³⁴ Js)

f = Frequency of electromagnetic waves (/s or Hz)

f = c / λ

c = speed of light

= 3.10⁸ m/s

λ = wavelength

The wavelength(λ) of purple light is 400 x 10⁻⁹ m, so the frequency :

$\tt f=\dfrac{c}{\lambda}\\\\f=\dfrac{3.10^8~m/s}{4.10^{-7}m}\\\\f=\boxed{\bold{7.5.10^{14}}/s}$

A student sets up the following equation to convert a measurement. (The ? stands for a number the student is going to calculate.

kvasek [131]

Answer:

1 cm/s

Explanation:

From the question given above,

the student is trying to convert 0.010 m/s to a number in cm/s.

Thus, we can convert 0.010 m/s to cm/s as illustrated below:

Recall:

1 m/s = 100 cm/s

Therefore,

0.010 m/s = 0.010 m/s × 100 cm/s ÷ 1 m/s

0.010 m/s = 1 cm/s

Therefore, 0.010 m/s is equivalent to 1 cm/s
