Hz is the green photon's frequency .
The distance between similar points (adjacent crests) in adjacent cycles of a waveform signal that is propagated in space is known as the wavelength. A wave's wavelength is often measured in meters (m), centimeters (cm), or millimeters (mm) (mm). The relationship between frequency and wavelength is inverse.
<h3>Given:</h3>
Wavelength of green light = 520 nm
f = c / λ
where, f = Frequency
c = Speed of light = 3 × 
m/s
λ = Wavelength of light
∴ f = c / λ
f = 
= 5.77 × Hz
Therefore, 5.77 × Hz is the green photon's frequency .

Answer:
ΔL = 0.66 m
Explanation:
The change in length on an object due to rise in temperature is given by the following equation of linear thermal expansion:
ΔL = αLΔT
where,
ΔL = Change in Length of the bridge = ?
α = Coefficient of linear thermal expansion = 11 x 10⁻⁶ °C⁻¹
L = Original Length of the Bridge = 1000 m
ΔT = Change in Temperature = Final Temperature - Initial Temperature
ΔT = 40°C - (-20°C) = 60°C
Therefore,
ΔL = (11 x 10⁻⁶ °C⁻¹)(1000 m)(60°C)
<u>ΔL = 0.66 m</u>

Mold
Explanation:
A mold is a cavity that is left behind in the rock after an organism hard part has been dissolved. These are important fossils that useful in relative dating.
- Some hard parts of organism are preserved in form of molds in soft sediments.
- The outline and important details of the hard part is preserved when the mold dissolves away.
- Fossil molds are representative on the internal outline of the hard parts of organisms.
- They are usually recognized as a part of body fossil in a section.
