Answer:
<em>The wavelength of water = 571.43 nm</em>
Explanation:
Refractive index of water = wave length of light in air/wave length of light in water
R.d = λ₁/λ₂.................. Equation 1
making λ₂ the subject of equation 1
λ₂ = λ₁/R.d...................... Equation 2
R.d = refractive index of water , λ₁ = wave length of light in air, λ₂ = wave length of light in water
<em>Given: R.d = 1.33, λ₁ = 760nm</em>
<em>Substituting these values into equation 2</em>
λ₂ = 760/1.33
<em>λ₂ = 571.43 nm</em>
<em>Therefore the wavelength of water = 571.43 nm</em>
Answer:
no deflection and net force is zero. Moving in same direction and with same speed
Explanation:
Charge = negative
the angle between the velocity vector and the magnetic field vector is 0°, so the force is given by
F = q v B Sin 0
F = 0
As the force is zero so the charge particle moves with the same velocity and in the same direction.
there is no deflection in the path of negatively charged particle.
It is the 'crest' part that the green arrow is identifying.
Bohr's equation for the change in energy is

where
h = Planck's constant
c == the velocity of light
λ = wavelength.
The velocity is related to wavelength and frequency, f, by
c = fλ
Let us examine the given answers on the basis of the given equations.
a. As λ increases, f decreases and ΔE decreases.
TRUE
b. As λ increases, f increases and ΔE increases.
FALSE
c. As λ increases, f increases and ΔE decreases.
FALSE
Answer:
As the wavelength increases, the frequency decreases and energy decreases.
