According to the trichromatic theory of color vision, also known as the Young-Helmholtz theory of color vision, there are three receptors in the retina that are responsible for the perception of color. One receptor is sensitive to the color green, another to the color blue and a third to the color red.
Hope this helps.
Answer:
λ = 6 10⁻⁷ m
Explanation:
This problem is a double slit interference spectrum where bright maxima are described by constructive interference.
d sin θ = m λ
Where d is the gap of the slits (d = 0.2 10⁻³ m), m is the maximum interference and λ is the wavelength
We used trigonometry to find the angle
tan θ = y / x
Since the angles in these experiments are very small we use
tan θ = sin θ / cos θ = sin θ
sin θ = y / x
We substitute
d y / x = m λ
λ = d y / m x
In this case the first maximum is m = 1
We substitute
λ = 0.2 10⁻³ 3.6 10⁻³ / (1 1.2)
λ = 6 10⁻⁷ m
The approximation made in this problem is that since the angles are small we approximate the tangent to the sine
Answer:
1.498×10⁵ Nm
Explanation:
From the question above,
Torque (T) = Force (F) × radius (r)
T = F×r............................. Equation 1
Where T = Torque, F = force, r = radius .
Given: F = 2.27×10⁵ N, r = 0.660 m
Substitute these values into equation 1
T = 2.27×10⁵×0.660
T = 1.498×10⁵ Nm
Hence the torque of the wheel is 1.498×10⁵ Nm
