(02.04 lc)
which type of electromagnetic radiation has a lower frequency than infrared radiation?
○ a gamma rays
○ b microwaves
○ c visible light
○ d x - rays
pregunta 3 (4 puntos)
(02.04 lc)
match each type of electromagnetic radiation to its description.
columna a

1. heat from warm objects, used to detect the location of objects
2. used in radar and to heat food
3. given off by very hot objects, such as the sun
4. all the radiation humans can see, ranging from red to violet

columna b
a. ultraviolet light
b. infrared radiation
c. microwaves
d. visible light

Explanation:

1. Electrons exhibit wave - particle duality, a well - established concept in physics.
2. In the electromagnetic spectrum, microwaves have a lower frequency than infrared radiation. Gamma rays, visible light, and X - rays have higher frequencies than infrared.
3. Infrared radiation is heat from warm objects and used for object detection. Microwaves are used in radar and for heating food. The sun gives off ultraviolet light as it is a very hot object. Visible light is the radiation humans can see, ranging from red to violet.

Answer:

1. a. True
2. b. Microwaves
3. 1. b
4. c
5. a
6. d
