Answer:

c = λf

E = h f

the characterization of electromagnetism is given as a function of energy or frequency.

Explanation:

In waves the frequency and donut length are related by the speed of the wave

c = λf

therefore the two quantities are not independent.

The energy of an electromagnetic wave is given by

E = h f

where h is the planck constant and f the frequency of the wave

This energy determines how the wave interacts with the surrounding medium. Low energy waves only create movement of the atomic nuclei and as the energy increases, the electrons are excited.

As a result of the above, the characterization of electromagnetism is given as a function of energy or frequency.

Meg goes swimming on a hot afternoon. When she comes out of the pool, her foot senses that the prevement is unbearably hot. Supp

mart [117]

1.Record her observation with the time it was hot.
2. Gather info about the pavement and its surroundings. Find out what it's made of and what its temp. is at different times of the day.
3. Come up with a hypothesis about why it is hot.
4. Design an experiment to test the hypothesis. If she thinks the Sun is responsible (which she should b smart enough to know), keep it covered during the day time and check it's temp.
5. Come up with a conclusion. If her hypothesis is not supported, design a new experiment or gather more info.

The magnetic field produced by a long straight current-carrying wire is

alexdok [17]

Answer:

proportional to the current in the wire and inversely proportional to the distance from the wire.

Explanation:

The magnetic field produced by a long, straight current-carrying wire is given by:

$B=\frac{\mu_0 I}{2 \pi r}$

where

$\mu_0$ is the vacuum permeability

I is the current intensity in the wire

r is the distance from the wire

From the formula, we notice that:

- The magnitude of the magnetic field is directly proportional to I, the current

- The magnitude of the magnetic field is inversely proportional to the distance from the wire, r

Therefore, correct option is

proportional to the current in the wire and inversely proportional to the distance from the wire.
