Both planets are similar in shape and have a rocky surface. Not sure about the phases though
Yes... This is a question google could answer. Just Saying
Explanation:
Question 1
1.The wires are made of conducting materials e.g copper
2. A light bulb is made of filament material e.g tungsten with gases enclosed in a glass material
3.The lens is made of transparent glass material
4 The reflector is made of plastic with silver lining
5. The exterior casing of most flash lights are made of plastic
Question 2.
1.Copper is used to conduct electric current from the battery to the bulb
2.The tungsten filament ignite the gases and causes it to glow
3. The lens covers the lamp on your flashlight so that the glass on the lamp
/bulbs does not get broken.
4.The reflector redirects the light rays from the lamp, creating a steady beam of light, which is the light you see emitting from the flashlight.
5. The exterior cases houses the entire assembly and makes the flash light handy for use
Answer:
in oil film λ = 303.57 10⁻⁹ m
in the water film λ = 319.55 10⁻⁹ m
Explanation:
When electromagnetic radiation reaches a material, its propagation is by a process that we call absorption and reflection,
when light reaches a surface it has a mass much greater than the mass of the photons (m = 0), therefore there is an elastic collision where the frequency does not change, due to the speed of light in the material medium changes, therefore the only possibility is that the wavelength in the material changes, to maintain the relationship
v = λ f
in the void we have
c = λ₀ f
we divide the two expression
c / v = λ₀ / λ
the refractive index is
n = c / v
n = λ₀ /λ
λ = λ₀ / n
let's calculate
in oil film
λ = 425 10⁻⁹ / 1.40
λ = 303.57 10⁻⁹ m
in the water film
λ = 425 10⁻⁹ / 1.33
λ = 319.55 10⁻⁹
those wavelengths are in the ultraviolet
