Waves: Absorption and reflection

Hard

(Originais Teachy 2023) - Question Hard of Physics

A student is conducting an experiment to study the phenomenon of reflection on a curved surface. For this, she is using an electronic signal generator to produce a one-dimensional wave in the form of an electromagnetic pulse, which is sent to a curved metal sphere. Which of the following statements is true?
a.
The electromagnetic pulse will be reflected by the curved metal sphere with the same wavelength as the incident pulse.
b.
The electromagnetic pulse will be reflected by the curved metal sphere with the same amplitude as the incident pulse.
c.
The electromagnetic pulse will not be reflected by the curved metal sphere.
d.
The electromagnetic pulse will be reflected by the curved metal sphere with a greater amplitude than the incident pulse.
e.
The electromagnetic pulse will be reflected by the curved metal sphere with the same frequency as the incident pulse.

When we use spherical lenses to study refraction in two-dimensional waves, we can observe some interesting phenomena such as the formation of images and chromatic aberrations, for example, caused by variations in the speed of light in the different incident light rays in the spherical lens. What is this variation in the speed of light called?

A thermal engine operating in cycles receives heat from a hot source and performs mechanical work, rejecting part of the heat to a cold source. Considering the cycle of a thermal engine that receives 1800 J of energy in the form of heat from the hot source, and knowing that its efficiency is 30%, calculate the work performed and the amount of heat rejected to the cold source, applying the first law of thermodynamics. Which alternative correctly presents the values of work performed and heat rejected (in Joules)?
