Describe the relationship between the wavelength and frequency of electromagnetic waves

Answers

Answer:

Frequency is inversely proportional to wavelength.

Explanation:

frequency is the number of oscillations in a unit of time.

Wavelength is the length between one oscillation and the next oscillation.

take two springs and 4 pins. (springs should have loops or hooks at terminals to attach to pins.)

Now get two pins and pin them at a certain distance apart.

take the first spring and attach its two terminals to the pins.

Repeat the above procedure, but double (increase the distance x2) the distance between two pins.

Now you have to measure how many coils are there within 5cm of the two springs.

you'll observe that the second spring has half the coils of the first spring within 5cm.

In here no. of coils is the frequency

5cm length is time.

distance between coil is the wavelength.

Explanation:

Answer:   I believe that the aluminum foil will slow down the process of melting because when you put ice in a thermal flask it takes a while to melt (also thermal things like flasks hold heat depending on the temperature) but on the other hand if you put it in bubble wrap it will most likely meal faster.

How do human cells resulting from meiotic division differ from human cells resulting from mitotic division?

Answers

The human cells resulting from meiotic division differ significantly from the cells resulting from mitotic division because :

Mitosis produces two diploid (2n)somatic cells that are genetically identical to each other and the original parent call,

whereas the meiosis produces four haploid (n) gametes which are genetically different from each other and the original parent cell as they are germ line cells.

Difference between mitosis and meiosis :

Mitosis is a fundamental process for life as our cell divides by this method in the development and growth of the body.

The cell duplicates all of its contents, including chromosomes and splits to form two identical daughter cells. This takes place in somatic cells.

Meiosis ensures humans have the same number of chromosomes as this takes place in germ cells like egg and sperm cell and produces half the number of chromosomes(n) and during fertilization they unite and become double that is 46 chromosomes.

when the concentration of a substance on one side of the membrane is different from its concentration on the other side of the membrane, the substance is said to exhibit a concentration

Answers

When the concentration of a substance on one side of the membrane is different from its concentration on the other side of the membrane, the substance is said to exhibit a concentration gradient.

CONCENTRATION GRADIENT:

Concentration gradient is a term used to refer to a difference in solute concentration on opposite sides of the membrane of an organism.

If the concentration on the external part of a cell is higher than that of the internal part of the cell, a concentration gradient is said to have occured.

Concentration gradient is the basis of osmotic movement of water into and out of a cell.

Therefore, When the concentration of a substance on one side of the membrane is different from its concentration on the other side of the membrane, the substance is said to exhibit a concentration gradient.
