Energy is inversely proportional to wavelength (E = hc/λ). If λ is doubled, E is halved.

Wavelength in medium = Wavelength in vacuum / n. Thus, λ = 600 nm / 1.33 ≈ 450 nm.

The energy of the electron in the ground state of hydrogen is -13.6 eV.

The direction of the magnetic force on a charged particle moving in a magnetic field is determined by the right-hand rule.

The total resistance in parallel is given by 1/R_total = 1/R1 + 1/R2. Thus, 1/R_total = 1/6 + 1/3 = 1/2, so R_total = 2 ohms.

In a parallel circuit, if one resistor fails, the other paths remain functional, allowing current to continue flowing.

In a parallel circuit, if one resistor fails, the total resistance decreases because there are fewer paths for current to flow.

Total resistance R_total = R1 + R2 = 4 Ω + 8 Ω = 12 Ω. Using Ohm's Law, I = V/R = 12 V / 12 Ω = 1 A.

In an adiabatic process, as the temperature decreases, the pressure also decreases due to the ideal gas law.

Sound travels slowest in air compared to water and solids like steel.

In a parallel circuit, adding more branches increases the total current because each branch provides an additional path for current to flow.

ΔU = Q - W = 500 J - 200 J = 300 J.

Using the first law of thermodynamics: ΔU = Q - W = 500 J - 200 J = 300 J.

Change in internal energy (ΔU) = Q - W = -200 J - 500 J = -300 J.

Using the formula for critical angle: sin(c) = n2/n1, we find c = sin^(-1)(1/1.5) ≈ 41.8 degrees.

Using the formula sin(c) = n2/n1, we find sin(c) = 1/1.5, thus c = sin^(-1)(2/3) ≈ 41.8 degrees.

The decibel scale is logarithmic; a sound 10 times more intense is 10 dB.

A sound that is 10 times more intense than the reference level is 10 dB.

The threshold of hearing is defined as 0 dB.

The direction of the magnetic field around a current-carrying conductor is given by the right-hand rule, which indicates a counterclockwise direction when viewed from the positive current side.

The spreading out of sound waves after passing through a narrow opening is known as diffraction.

Energy (E) = h * frequency = 6.626 x 10^-34 J·s * 5 x 10^14 Hz = 3.31 x 10^-19 J.

In series, the equivalent resistance is the sum: R_eq = R1 + R2 = 4 Ω + 6 Ω = 10 Ω.

In series, the equivalent resistance is the sum: R_eq = R1 + R2 = 4 Ω + 6 Ω = 10 Ω.

The formula for equivalent resistance in parallel is 1/R_eq = 1/R1 + 1/R2. Thus, 1/R_eq = 1/4 + 1/6 = 5/12, so R_eq = 12/5 = 2.4Ω.

The formula for equivalent resistance (R_eq) of two resistors in parallel is given by 1 / (1/R1 + 1/R2).

Using the lens formula 1/f = 1/v - 1/u, we find f = -20 cm.

The electric power can be calculated using multiple formulas: P = IV (power = current × voltage), P = I^2R (power = current squared × resistance), and P = V^2/R (power = voltage squared / resistance).

The capacitance (C) of a parallel plate capacitor is given by C = εA/d, where ε is the permittivity, A is the area of the plates, and d is the distance between them.

The power consumed in an electrical circuit is given by the formula P = IV, where P is power, I is current, and V is voltage.
