How many photons does a 60 watt bulb? so, #photons= 60/3.2EXP(-19)=1.87EXP20 photons per second. How do you calculate the number of photons emitted per minute? Find the number of photons emitted per minute by a 25W source of monochromatic light of wavelength 5000Å. Use h=6.63×10-34Js. Step by step solution by experts to help you in […]
What does burning sulfur look like?
What does burning sulfur look like? When burned, sulfur produces a blue flame and sulfur dioxide gas — a common pollutant, according to the Environmental Protection Agency. Why does Sulphur burn blue? “It is due to the combustion of sulfuric gases in contact with air at temperatures above 360°C.” Exposed to the oxygen present in […]
What is the maximum stacking height?
What is the maximum stacking height? Items of all types should be stable and self supporting. Lumber: Adhere to OSHA’s guidelines for stacking heights: 16 feet (manually); 20 feet (forklift) maximum stacked heights. Remove screws and nails. Bags: Stack them in interlocking rows. What do you understand by maximum stacking height? Stacking height is the […]
What are the five properties of waves?
What are the five properties of waves? There are many properties that scientists use to describe waves. They include amplitude, frequency, period, wavelength, speed, and phase. Each of these properties is described in more detail below. When drawing a wave or looking at a wave on a graph, we draw the wave as a snapshot […]
What are the disadvantages of digital thermometer?
What are the disadvantages of digital thermometer? The advantages of digital thermometers are that they are inexpensive, easy to read, require very little maintenance and give an accurate reading. The disadvantage is that they get damaged easily if dropped and the battery powering them eventually runs out. What is the advantage of digital thermometer over […]

Do insects have six legs?
Do insects have six legs? Insects have six legs and two antennae, and their body is made up of three main regions: head, thorax, and abdomen. They have an exoskeleton that contains sense organs for sensing light, sound, temperature, wind pressure, and smell. Insects have only six legs. How do bugs move without muscles? In […]
What is period amplitude and frequency?
What is period amplitude and frequency? amplitude: maximum displacement from the equilibrium position of an object oscillating around such equilibrium position. frequency: number of events per unit of time. period: time it takes to complete one oscillation. Can a frequency be negative? Real sinusoidal signals have only positive frequency. Negative frequency is an idea associated […]
What happens to light when you increase the wavelength?
What happens to light when you increase the wavelength? An increase in frequency produces a proportional decrease in the wavelength of light with a corresponding increase in the energy of the photons that make up the light. Thus as frequency increases (with a corresponding decrease in wavelength), the photon energy increases and visa versa. What […]
