Longer wavelengths of light, such as , have energy than shorter wavelengths, such as

Micro and radio waves.

Lower energy.

Gamma rays.

Explanation:

The electromagnetic spectrum is the range of frequencies of electromagnetic radiation and their respective wavelengths.

Ionising radiation os defined as the energy required of photons of a wave to ionize atoms, causing chemical reactions.

The energy of the wave depends on both the amplitude and the frequency. If the energy of each wavelength is a discrete packet of energy, a high-frequency wave will deliver more of these packets per unit time than a low-frequency wave. In summary, the longer the wavelength, the lower the energy to ionise.

The velocity of a wave is directly proportional to the frequency of that wave.

c = f * lambda

Where,

c = velocity of the wave

f = frequency of the wave = 1/time

Lambda = wavelength.

From the above expression, the longer the wavelength, lambda the shorter the frequency.

Examples of waves with longer wavelengths are, micro and radio waves, while radiations with shorter wavelengths like gamma rays.

The correct option is a.

Explanation:

In the parallel combination of the circuit, the voltage in the circuit is same but the amount of current flowing in the circuit is different across the resistance.

The expression for the total amount of current in the parallel combination is as follows;

Here, I is the total amount of current and are the current flowing across resistances.

In the series combination of the circuit, the current flowing in the circuit is same but the voltage in the circuit is different across the resistance.

The expression for the total voltage in the series combination of the circuit is as follows;

Here, V is the total voltage and are voltages flowing across resistances.

In the given problem, it is asked to determine the quantities which are equal to total of the individual values within a circuit.

Therefore, the option a is correct.
