Answer:
Light of wavelength 200 nm will have lowest frequency in while traveling through diamond.
Explanation:
Speed of the light in vacuum = c
Relation between speed of light , wavelength (λ) and frequency (ν);
Speed of light in a medium = c' = c/n
...[1]
Where : n = refractive index of a medium
So, the medium with greater value of refractive index lower the speed of light to greater extent.
From [1] , we can see that frequency of light is inversely proportional to the refractive index of the medium :
This means that higher the value of refractive index lower will be the value of frequency of light in that medium or vice-versa.
According to question, light of wavelength 200 nm will have lowest frequency in while traveling through diamond because refractive index of diamond out of the given mediums is greatest.
Increasing order of refractive indices:
Decreasing order of frequency of light 210 nm in these medium :
Answer:
Developer
Explanation:
A <u><em>developer </em></u>is an oxidizing agent that, when mixed with an oxidation hair color, supplies the necessary oxygen gas to develop color molecules and create a change in hair color.
Mostly hair colors are used to dye the gray hairs. Hair colors are mixed with developer which is act as oxidizing agent. The wisely used developer is hydrogen peroxide. The hair color is made of ammonia and oxidative tints.
These tints consist of small precursors of uncolored dye. These combined with hydrogen peroxide and form large tint molecule. These are then diffuse into cortex of hair and can not get off during shampoo.
These are termed as permanent hair colors.
<u>The Concept:</u>
We are given the density of a sample of the metal = 11.4 grams / cm³
and we need to find the volume occupied by a sample of 30.5 grams
For this solution, we will use dimensional analysis
from the given information, we can also say that the density of the metal is:
1 cm³ / 11.4 grams
If we multiply this value by 30.5 grams, the 'grams' in the numerator and the denominator will cancel out and we will be left with the volume occupied by 30.5 grams of the metal
<u>Solving for the volume:</u>
X 30.5 grams = (30.5 / 11.4) cm³
Volume of 30.5 grams of the sample = 2.68 cm³
Answer:
Less soil erosion
Explanation:
Due to the low amount of rainfall in this region, it is easier to say that the region compared to other ecoregion will suffer less soil erosion.
Erosion is usually the washing away of the top layer of the soil. Rainfall is one of the most important element that causes erosion. Surface runoff for an extended period of time can remove the topmost layer of the earth on which plant can grow. This starves the soil of its rich nutrients and minerals.
Warm air is lighter than cold air so hot air will rise as cold air sinks
