What is the difference between loudness and frequency? Frequency (the number of vibrations or sound waves per second) is measured in Hertz (Hz). A sound that is 4,000 Hz (like the sound the letter “F” makes) has 4,000 waves per second. Intensity (loudness) is the amount of energy of a vibration, and is measured in […]
Is renewable natural gas the future?
Is renewable natural gas the future? If we could harness methane-producing waste to create an electricity source, we could reduce the amount of methane in the atmosphere and also utilize a new renewable power source. Renewable natural gas has a future in energy and may potentially help relieve the world’s current waste problem. Why is […]
What does hypothesis mean in simple terms?
What does hypothesis mean in simple terms? A hypothesis is a suggested solution for an unexplained occurrence that does not fit into current accepted scientific theory. The basic idea of a hypothesis is that there is no pre-determined outcome. What is the best definition for the word prediction? A prediction is what someone thinks will […]

What is the difference between solar time and solar day?
What is the difference between solar time and solar day? The sidereal day is measured with respect to the stars, while the solar day is the length of time measured from noon to noon. By noon, we mean the time when the Sun passes the celestial meridian, reaching its maximum height in the sky. How […]

Is a guitar string a standing wave?
Is a guitar string a standing wave? A guitar string sound consists of standing waves: the fundamental and overtones. The fundamental wavelengh is twice the length of the vibrating part of the string. What type of wave does a guitar make? Longitudinal Waves What is the frequency of low E on a guitar? 82 Hz […]
How do you convert C to F fast?
How does frequency affect interference?
How does frequency affect interference? A higher frequency corresponds to a shorter wavelength. Waves of shorter wavelength spread out (diffract) less after passing through the slits, and the short wavelength leads to a smaller angle at which constructive interference (one wavelength path difference between the two waves) will occur. What is interference effect? Interference, in […]
What are the four main blood vessels?
What are the four main blood vessels? The major blood vessels connected to your heart are the aorta, the superior vena cava, the inferior vena cava, the pulmonary artery (which takes oxygen-poor blood from the heart to the lungs where it is oxygenated), the pulmonary veins (which bring oxygen-rich blood from the lungs to the […]
