Why does frequency affect wavelength? The number of complete wavelengths in a given unit of time is called frequency (f). As a wavelength increases in size, its frequency and energy (E) decrease. From these equations you may realize that as the frequency increases, the wavelength gets shorter. As the frequency decreases, the wavelength gets longer. […]
Why does oxygen attract electrons more strongly than hydrogen?
Why does oxygen attract electrons more strongly than hydrogen? The oxygen atom attracts the shared electrons more strongly than the hydrogen atoms do because the nucleus of the oxygen atom has more positively charged protons. As a result, the oxygen atom becomes slightly negative in charge, and the hydrogen atoms become slightly positive in charge. […]
What steps are taken for energy and water conservation in hotel?
What steps are taken for energy and water conservation in hotel? HOUSE KEEPING DEAPRTMENT Turn off guest room lights when rooms are not physically occupied. Use minimum lighting when making up and cleaning rooms. Turn off corridor lights, or reduce it to 50% when natural light is available. Turn off lights in linen rooms, storage […]
Is NH3 a dipole?
What type of reaction is the reaction of magnesium with oxygen?
What type of reaction is the reaction of magnesium with oxygen? Oxygen and magnesium combine in a chemical reaction to form this compound. After it burns, it forms a white powder of the magnesium oxide. Magnesium gives up two electrons to oxygen atoms to form this powdery product. This is an exothermic reaction. What happens […]
What is 1 dB?
What is 1 dB? Decibel (dB), unit for expressing the ratio between two physical quantities, usually amounts of acoustic or electric power, or for measuring the relative loudness of sounds. One decibel (0.1 bel) equals 10 times the common logarithm of the power ratio. What is black noise? Black noise is an informal term used […]
What is a specific and nonspecific immune response?
What is a specific and nonspecific immune response? Nonspecific protective mechanisms repel all microorganisms equally, while the specific immune responses are tailored to particular types of invaders. These immune mechanisms also help eliminate abnormal cells of the body that can develop into cancer. What are the two different specific immune responses? There are two types […]
Why are most plants green in color?
Why are most plants green in color? The longer answer lies in the details of photosynthesis, the electromagnetic spectrum, energy and “special pairs” of chlorophyll molecules in each plant cell. As such, plants look green because they absorb red light most efficiently and the green light is reflected. Who named Chlorophyll is a green Coloured […]
What is the difference between Formula mass and molecular mass?
What is the difference between Formula mass and molecular mass? The formula mass of a substance is the sum of the average atomic masses of each atom represented in the chemical formula and is expressed in atomic mass units. The formula mass of a covalent compound is also called the molecular mass. The mass in […]
Which color model is best suited for human interpretation?
Which color model is best suited for human interpretation? The HSI Color Model HSI stands for hue, saturation, intensity. This model is interesting because it can initially seem less intuitive than the RGB model, despite the fact that it describes color in a way that is much more consistent with human visual perception. What does […]
