Which of the visible spectrum colors corresponds to the largest energy change?

User Avatar

Asked by Wiki User

The color violet corresponds to the largest energy change in the visible spectrum. It has the shortest wavelength and highest frequency, resulting in higher energy compared to other visible colors like red or blue.

How can a contamined wire loop be cleaned?

User Avatar

Asked by Wiki User

A contaminated wire loop can be cleaned by heating it to a high temperature until the contaminants are burned off. Another method is to immerse the loop in a cleaning solution such as alcohol or bleach, followed by thorough rinsing with distilled water. Regularly inspecting and cleaning the wire loop after each use can help prevent heavy contamination buildup.

How is cool cayenne produced?

User Avatar

Asked by Wiki User

Cool cayenne is produced by selectively breeding cayenne peppers for a milder heat profile while still retaining the characteristic flavor. This process involves isolating and propagating plants with lower capsaicin levels to create a variety that delivers a more manageable spiciness. Cool cayenne peppers are then grown and harvested like traditional cayenne peppers.

The visible spectrum is the range of electromagnetic radiation that is visible to the human eye. It consists of colors that can be seen from red through violet, with red having the longest wavelength and violet the shortest. This range of colors makes up the rainbow.

What was the price of light bulb in nineteenth century?

User Avatar

Asked by Wiki User

In the early 19th century, the price of a light bulb would have been quite high due to the novelty and complexity of the technology. However, the exact price would have varied depending on factors such as the type of bulb and the manufacturer. Generally, light bulbs were considered luxury items until they became more affordable with advancements in manufacturing and technology later in the century.

How do you turn the dome lights the lights underneath the dash when they don't go off after getting out of the car?

User Avatar

Asked by Wiki User

If the dome lights or lights under the dash don't turn off after exiting the car, you can try closing all doors properly and ensuring the parking brake is engaged. If they still do not turn off, there may be a faulty door switch or wiring issue that needs to be addressed by a mechanic. You can also try manually turning off the lights using the light switch if applicable.

What is luminous mean?

User Avatar

Asked by Wiki User

ANSWER:Luminous could also mean 'full of light or illuminated'. For example: luminous hands of a clock. Here, luminous denotes shiny or that give light. In the example: luminous room; luminous indicates well-lighted. Something that is clear or easy to understand is also termed luminous. Fro example: luminous prose or luminous theory. Luminous could also mean inspiring, intelligent, or enlightened.

What is the spectrum of the moon?

User Avatar

Asked by Wiki User

The moon reflects sunlight, so its spectrum is similar to that of the Sun. It follows a blackbody curve with peaks in the visible range. The moon also shows absorption lines from elements in its surface materials.

Is uv light at night enough time for turtle?

User Avatar

Asked by Wiki User

No, turtles need a basking light or heat lamp during the day to maintain their body temperature and to help with digestion and metabolizing calcium. UV light at night is not sufficient for turtles. It is important to provide a proper light cycle for your turtle's health and well-being.

Can resistors keep a magnetic coil from heating?

User Avatar

Asked by Wiki User

Resistors are not typically used to directly control the heating of a magnetic coil. The heating of a coil is primarily controlled by the amount of current flowing through it. Resistors are used in circuits to limit current flow and voltage in specific parts of a circuit, but they might not be the best component to control the heating of a coil.

What happens to your muscles when you pick up something light you expect to be heavy?

User Avatar

Asked by Wiki User

When you pick up something light that you expect to be heavy, your nervous system might activate more muscle fibers than necessary to prepare for the heavier load. This can result in your muscles feeling more tense or firing more intensely than needed for the task at hand.

How did Rutherford contribute to light?

User Avatar

Asked by Wiki User

Rutherford is known for his contributions to the field of nuclear physics, particularly the discovery of the atomic nucleus through his gold foil experiment in 1911. This experiment led to the development of the planetary model of the atom, which greatly influenced our understanding of the structure of the atom. However, his work was mainly focused on the study of radioactivity and the behavior of alpha particles, rather than directly related to light.

How is light redirected in a periscope?

User Avatar

Asked by Wiki User

Light enters the periscope through one end and reflects off a series of mirrors inside which are set at specific angles. The mirrors then redirect the light so that it exits through the other end of the periscope, allowing the viewer to see objects or scenes that are not in a direct line of sight.

Who discovered the light bulb and when?

User Avatar

Asked by Wiki User

Thomas Edison is credited with inventing the first commercially practical incandescent light bulb in 1879. However, it is important to note that there were earlier versions of electric lighting created by other inventors before Edison's successful design.

Why does a Mazda b3000 abs light come on?

User Avatar

Asked by Wiki User

The ABS light in a Mazda B3000 can come on due to issues with the ABS system, such as a faulty wheel speed sensor, a malfunctioning ABS module, or low brake fluid. It is recommended to have the ABS system checked by a professional mechanic to diagnose and repair the issue.

What causes the bending of light?

User Avatar

Asked by Wiki User

The bending of light is caused by a change in the speed of light as it travels through different mediums, known as refraction. This change in speed causes the light to change direction at the boundary between two materials with different optical densities. Additionally, gravitational forces from massive objects can also cause light to bend through a phenomenon known as gravitational lensing.

Does the moon give off light or reflect it?

User Avatar

Asked by Wiki User

The moon reflects light just as any other object reflects light that falls upon it. Only about 7% of the light from the Sun is reflected off the moon's surface == ==
The moon reflects the light from the sun.

How long is a red light?

How do you use Japanese light bulb 100V in Malaysia which is 240V?

User Avatar

Asked by Wiki User

To use a Japanese light bulb (100V) in Malaysia (240V), you will need to use a step-down transformer to convert the voltage from 240V to 100V. This will allow the light bulb to function properly without being damaged by the higher voltage. Make sure to use a transformer that is rated for at least the wattage of the light bulb to ensure safe operation.

Can a coffee table be slightly higher than the sofa?

User Avatar

Asked by Wiki User

Yes, a coffee table can be slightly higher than the sofa for added convenience and functionality. This may make it easier to reach items on the table without straining, and can also create a visually appealing contrast in the room. Just make sure it's not too high to disrupt the overall balance and comfort of the space.

Astronomical telescopes used for viewing visible light may be divided into two general classes refractors and reflectors Describe the main components of each?

User Avatar

Asked by Wiki User

Refracting telescopes have a lens at the front to gather light and focus it, while reflecting telescopes use a curved mirror at the back to collect and focus light. The main components of a refracting telescope are the objective lens, eyepiece, and tube, while the main components of a reflecting telescope are the primary mirror, secondary mirror, and housing.

Light is important for various reasons. It helps plants undergo photosynthesis, providing them with energy, and also regulates our circadian rhythms, influencing our sleep-wake cycles. Additionally, light allows us to see and perceive the world around us, enhancing safety and productivity.

When an object appears to be yellow what color of the spectrum is reflected?

User Avatar

Asked by Wiki User

When an object appears yellow, it is reflecting yellow light waves predominantly from the visible spectrum. This means that the object is absorbing other colors of light (like blue and red) and reflecting the yellow light, which is perceived by our eyes as the color yellow.
