Final answer:
The truth value of the statement 'There are only pink buttons, blue buttons, and green buttons' cannot be determined without additional context. If other colors are present, the statement would be false. Key corrections include ultraviolet light inducing the photoelectric effect and green light having a lower frequency and longer wavelength than blue light.
Step-by-step explanation:
It seems like there's a statement with missing information about the available button colors. Without additional context, it's impossible to determine if the statement 'There are only pink buttons, blue buttons, and green buttons' is true or false. For example, it might be false if there are other button colors present than the ones listed. It's important to have either a clear reference, such as an image or a description, that confirms only those colors are present, or the statement may need to be corrected to include other colors if there are indeed more.
In regard to the statements provided for reference:
- (13) The statement 'Visible light is the only type of electromagnetic radiation that can cause the photoelectric effect' is false. Ultraviolet light can also cause the photoelectric effect.
- (c) The correct statement about a blue filter is that it absorbs all visible light other than blue light.
- (b) The frequency of green light is lower than the frequency of blue light and the wavelength of green light is longer than the wavelength of blue light. This statement is false as presented.
