Answer: 2.13 E 4 J

Explanation: Heat absorbed = mass * specific heat capacity * change in temperature

= 0.5 * 387 * (400 - 290) J

= 0.5 * 387 * 110 J = 21285 J = 2.13 E 4 J

Which of the following is true about green light? a) It has a greater frequency than red light and blue light. b) It has a small
lesantik [10]

Answer:

c) It has a greater frequency than red light but a smaller frequency than blue light.

Explanation:

According to the relation:

c = frequency × Wavelength

The higher the frequency, the lower the value of wavelength

The order of wavelength is:

Violet < Indigo < Blue < Green < Yellow < Orange < Red

Stated above, frequency is inversely proportional to the wavelength. Thus, the order of wavelength is:

Violet > Indigo > Blue > Green > Yellow > Orange > Red

Thus,

<u>Green light has lower frequency than blue light and higher than red light.</u>
