Green light has a moderate frequency compared to other colors in the visible light spectrum. It falls between blue and yellow light in terms of frequency.
Generally, violet light has a slightly higher refractive index compared to other colors in the visible spectrum. This means it bends more when passing from one medium to another, such as from air to water, compared to other colors like red or green.
Blue has the highest energy among the colors listed, followed by yellow, red, and green. This is because blue light has a shorter wavelength and higher frequency compared to the other colors.
Some traditional thermometers do contain mercury, but newer models typically use a safer alternative like alcohol or digital sensors. Mercury is toxic if ingested or exposed to skin, so it's important to handle mercury-containing thermometers carefully and dispose of them properly.
