Answer:

It is not a property of light. It is your eyes and brain.

Specifically, the three kinds of cone cells in our eye that are sensitive to different ranges of the electromagnetic spectrum. The fact that there are three means that color is three dimensional, and is the reason the pure colors form a circle even though the spectrum of wavelengths is linear.

Visible light is part of the electromagnetic spectrum; light waves of different frequencies and wavelengths are distinguished as colors by the human eye. A prism can separate the colors of white light (dispersion) because different frequencies of light have different refractive indices for a given material.

How is silver, gold, and bronze different.

joja [24]

Answer:

Silver is a malleable and ductile metal having atomic number 47 and symbol Ag. Gold on the hand has atomic number 79 and symbol Au. It is also ductile and malleable. Both are soft and lustrous in nature. Both are transition metals.

Bronze is an alloy of majority of copper and some amount of tin. Formation of alloy enhances the properties of the metal and its industrial use. Bronze is harder than copper and easily fusible and easy to cast. It is resists corrosion.

Silver and gold have different atomic numbers, different colors. Both are transition elements where as Bronze is an alloy.

What do you notice about earths axis during the winter solstice

MrRa [10]

The Earth's axis is tilted "away" from the Sun in the hemisphere. where it's winter. The daytime is very short. That's because the Earth's axis is tilted "away" from the Sun in the hemisphere.

The Golden Gate Bridge in San Francisco has a main span of length 1.28 km, one of the longest in the world. Imagine that a steel

Valentin [98]

Answer:

361.46 N

Explanation:

$\alpha$ = Coefficient of thermal expansion = $11\times 10^{-6}\ /^{\circ}C$

Y = Young's modulus for steel = $20\times 10^{10}\ Pa$

A = Area = $3.1\times 10^{-6}\ m^2$

$L_0$ = Original length = 1.28 km

$\Delta T$ = Change in temperature = $45-(-10)$

Length contraction is given by

$\Delta L=\alpha L_0\Delta T$

Also,

$\Delta L=\dfrac{L_0T}{YA}$

$\alpha L_0\Delta T=\dfrac{L_0T}{YA}\\\Rightarrow T=\alpha \Delta TYA\\\Rightarrow T=11\times 10^{-6}\times (43-(-10))\times 20\times 10^{10} \times 3.1\times 10^{-6}\\\Rightarrow T=361.46\ N$
