What is electromagnetic spectrum explain?
The electromagnetic spectrum is a continuum of all electromagnetic waves arranged according to frequency and wavelength. The sun, earth, and other bodies radiate electromagnetic energy of varying wavelengths. The spectrum of waves is divided into sections based on wavelength.
What color has the longest wavelength?
red light
On one end of the spectrum is red light, with the longest wavelength. Blue or violet light has the shortest wavelength. White light is a combination of all colors in the color spectrum. It has all the colors of the rainbow.
What is the highest frequency color?
violet
When it comes to visible light, the highest frequency color, which is violet, also has the most energy. The lowest frequency of visible light, which is red, has the least energy.
Why does a banana appear yellow?
When a fruit comes into contact with ethylene gas, the acids in the fruit start to break down, it becomes softer, and the green chlorophyll pigments are broken up and replaced—in the case of bananas, with a yellow hue.
Is light invisible?
Most types of light are invisible to our eyes. Colors are our brains’ way of interpreting the wavelength of light: how far the light travels before the wave pattern repeats itself. But the colors we see—called “visible” or “optical” light—are only a small sample of the total electromagnetic spectrum.
How big is a nanometer of visible light?
A nanometer is a millionth of a millimeter or a billionth of a meter (There are 25,400,000 nanometers in a single inch). The human eye see visible light when the energy has wavelengths between approximately 400 and 700 nanometers. That’s wavelengths between 400 and 700 billionths of a meter.
Which is the latest model of HP Spectre?
The latest one, a model HP likes to call Spectre x360 13, sees a massive reduction in the laptop’s top and bottom bezels. It also comes with Intel’s 10th Gen Ice Lake U (10-nanometre) CPU and 4G LTE connectivity. Let’s see how it did at the Digit Test Centre.
How long does the HP Spectre battery last?
On our standard battery benchmark test, the review unit lasted 4 hours, 57 minutes. That’s not only a new record score for HP’s Spectre series in our books but also the highest score we have seen this entire year in the category of convertible laptops.
