Answer:

1 true

2 true

3 true

4 false = decreasing wavelength and increasing energy and frequency

5 true

6 false = On one end of the spectrum is red light, with the longest wavelength. Blue or violet light has the shortest wavelength.

7 true

8

9 false = UVA radiation is what makes people tan.

10 true

11 true

12 true -  it is always upright, and of the same shape and size as the object it is reflecting.

13 true

14 true =  magnification of a plane mirror is always 1 and it forms images which are always of the same size as the object.
