Answer:
B = E/c = 14.04T₁ = 11 pT
Explanation:
We know c = E/B where E = maximum electric field = 3.30 × 10⁻³ V/m, B = maximum magnetic field and c = speed of light
B = E/c also c = fλ = λ/T where λ = wavelength = 235 μm = 235 × 10⁻⁶ m and T = period
c = λ₁/T₁ = λ₂/T₂ T₂ = 2.8T₁ where λ₁,λ₂ are the initial and final wavelengths and T₁,T₂ are the initial and final periods.
T₁ = λ₁/c = 235 × 10⁻⁶ m/3 × 10⁸ m/s = 7.833 × 10⁻¹³ s = 0.7833 ps
T₂ = 2.8T₁ = 2.8 × 7.833 × 10⁻¹³ s = 21.93 × 10⁻¹³ s = 2.193 ps
λ₁/T₁ = λ₂/2.8T₁
λ₂ = 2.8λ₁ = 2.8 × 235 μm = 658 μm
c = λ₂/T₂ = 2.8λ₁/2.8T₁ = λ₁/T₁ , since the speed of light c is constant.
B = E/c = E/λ₁/T₁ = ET₁/λ₁
B = ET₁/λ₁ = 3.30 × 10⁻³ V/m × T₁/235 × 10⁻⁶ m = 14.04T₁ Tesla
B = 14.04 × 7.833 × 10⁻¹³ s = 10.99 × 10⁻¹² T ≅ 11 pT
Answer:
Conduction occurs more readily in solids and liquids, where the particles are closer to together, than in gases, where particles are further apart. ... As these molecules collide, thermal energy is transferred via conduction to the rest of the pan.
Explanation:
Metals have tightly packed atoms which can easily pass on their kinetic energy and also have free moving electrons.
Answer: C
high; large
Explanation:
The wave energy is related to its amplitude and frequency.
The wave energy is proportional to the amplitude of the wave. So, wave with the most energy will have high amplitude.
Also, frequency is related to wave energy. The larger the frequency, the more the energy of the wave.
Therefore, The waves with the MOST energy have high amplitudes and large
frequencies.
Answer:
n = 1.5
Explanation:
The speed of light in vacuum is 300000000 m/s
The speed of light in glass is 200000000 m/s
We need to find the refractive index of the glass.
We know that, the ratio of speed of light in vacuum to the speed of light in medium is equal to refractive index of the medium.
So, the refractive index of the glass is 1.5.
