Answer:
The correct answer is B. Statements (i) and (ii) are true.
Explanation:
Fisrt statement:
Electromagnetic radiation such as wave, wavelength λ and oscillation frequency ν are related by a constant, the speed of light. The equation is given by:
[tex]c= \lambda \nu[/tex]
So the first statement is true.
Second statement:
[tex]c=\lambda \nu\\c= 3.0 A \times 1.0\times 10^{18} Hz\\c= 3.0\times 10^{-10} m \times 1.0\times 10^{18} s^{-1}\\c=3\times 10^8 \frac{m}{s}[/tex]
The value of c in the vacuum is 3×10⁸ m/s. Hence, the second statement is true.
Third statement:
The speed of any electromagnetic radiation is constant regardless the type of radiation.
Hence, the third statement is false.
