That depends on the wavelength of the electromagnetic radiation.

-- If the waves are long, then we use them for radio, TV, and cellphones.

-- If the waves are shorter than that, then we use them for GPS in the car.

-- If the waves are shorter than that, then we use them to heat meatloaf
in the microwave oven.

-- If the waves are shorter than that, then they warm us and they
make our plants grow ... like the ones we eat.

-- If the waves are shorter than that, then our eyes use them to see with.

-- If the waves are shorter than that, then they tan our skin.

-- If the waves are shorter than that, then they can cause cancer on
our skin.

-- If the waves are shorter than that, then they can cause cancer and
other diseases in places inside our body.

During the new moon phase, why is the Moon not visible in the sky?

katrin [286]

Answer:

<em>During the new moon phase, the moon is not visible because Sometimes it can be detected by noting the visible absence of the stars that it blocks. Additionally, during the new moon, sometimes enough light is reflected off the surface of the Earth that the disk of the moon is faintly visible</em>

When using higher magnification, you need more light. which parts of the microscope can be adjusted to provide more light, and h

Increased lamp voltage is achieved by turning the light intensity dial.

To enlarge the diameter of the hole and let more light through the slide, the iris diaphragm was modified.

Condenser: Position it higher and closer to the slide's bottom to better direct light to the centre of the slide.

<h3>How do you adjust the light level on a microscope?</h3>

Utilize the brightness adjustment knob to change the brightness. Turn the brightness control knob while looking through the eyepieces to make sure there is no glare in the field of view.

Use a daylight balancing filter if your compound microscope has a certain sort of illumination. It typically rests directly on top of the luminator or in a filter holder above the light. This filter is blue.

The daylight balancing filter will correct the colour temperature and produce a higher-quality image if your microscope is lighted by tungsten or halogen (and a better colour image). This blue filter is not necessary if your microscope is an LED.

4) You have a 10 ohm resistor connected in series with an ammeter. The voltage applied to the whole circuit is 1.2 volts. At the

GuDViN [60]

Answer:

0.6 Ω

Explanation:

As shown in the diagram below,

Since the resistance and the ammeter are connected in series,

(i) The same amount of current flows through them.

(ii) The sum of their individual individual voltage is equal to the total voltage of the circuit.

Applying ohm's law,

V = IR................ Equation 1

Where V = Voltage across the ammeter, I = current flowing through the ammeter, R = resistance of the ammeter.

make R the subject of the equation

R = V/I............... Equation 2

Given: V = 1.2-0.9 = 0.3 V, I = 0.5 A.

Substitute into equation 2

R = 0.3/0.5

R = 0.6 Ω
