What is the frequency of red? The visible spectrum colour* wavelength (nm) frequency (1014 Hz) red 650 4.62 orange 600 5.00 yellow 580 5.16 green 550 5.45 Which of the color has the highest frequency and energy? violet Does red light travel further than blue? The individual components of light are called the spectrum. Blue […]

What does the 4 in 3/4 mean in music? The 3/4 time signature means there are three quarter notes (or any combination of notes that equals three quarter notes) in every measure. As we learned in the prior lesson, because there is a 4 on the bottom, the quarter note gets the beat (or pusle). […]

What is gravitational potential energy in simple words? Gravitational potential energy is the energy stored in an object as the result of its vertical position or height. The energy is stored as the result of the gravitational attraction of the Earth for the object. What is the meaning of gravitational potential? The gravitational potential at […]

What happens if your goals are not aligned with your values? If your dreams and goals are not in alignment with your values and purpose, it’ll be very difficult to achieve them as you’ll be fighting an internal battle the entire way. How do you align your life with your values? Here’s how to really […]

Which has the longest wavelength Brainly? Red Which color has the shortest wavelength Brainly? violet Which color has the highest frequency the shortest wavelength? Violet Does light vibrate at a low frequency? Our eyes perceive different wavelengths of light as the rainbow hues of colors. Red light has relatively long waves, around 700 nm long. […]

How many car lengths should you leave? Figure one car length for every ten miles an hour,” Barndt said. “So if you’re doing 55 miles an hour you should have six car lengths between you so that if something happens to the car in front of you, you have time to stop or react.” The […]

When discussing magnetic fields we could say that 2 points? When discussing magnetic fields we could say that metals can become magnetic if they have many spinning electrons that create magnetic fields. metals are magnets because they have more electrons than non–magnetic materials. non–paired electrons spin in opposite directions creating a magnetic field. What are […]

What is an example of emergent literacy? Examples of emergent literacy activities include engaging in shared storybook reading, pretending to write or draw, incorporating literacy themes into play, and engaging in oral wordplay such as rhyming. Parents read to children who are very young before they can verbally participate. What are the 5 pillars of […]

How do you explain solubility to a child? Solubility is a measure of how much solute can be dissolved into a liter of solvent. Think of the example of water and salt. If you keep pouring salt into water, at some point the water isn’t going to be able to dissolve the salt. What is […]

Why incandescent bulbs are better? Incandescent bulbs cost much less than their energy-efficient alternatives – mainly CFLs (compact fluorescent lamps) and LEDs (light emitting diodes). Incandescents are inefficient – 90% of the energy goes toward heat and only 10% toward light. Incandescents also don’t last as long as CFLs and LEDs. What are the disadvantages […]
