Set the proportion up 37.50/105.50 = 41/x and solve for x
The correct answer of this question is : A) Radio waves have longer wavelengths, lower frequency, and lower energy than ultraviolet waves and x-rays.
EXPLANATION :
Before going to answer this question, first we have to know the electromagnetic spectrum.
Electromagnetic spectrum is the arrangement of electromagnetic waves in the ascending order of frequency or descending order of wavelength.
When the waves are arranged in the ascending order of their frequency, then perfect order is given below as such -
Radio wave < Micro wave < Infrared wave < Visible light < U.V ray< X-ray < Gamma ray .
Hence, we see that radio wave has the least frequency, and gamma ray has the most frequency.
We know that wavelength and frequency are inversely are inversely proportional to each other. Hence, radio wave has more wavelength and less frequency.
The wave having more frequency is more energetic. Hence, gamma is more energetic and radio wave is less energetic .

Explanation:
given
R = 1.5 cm
object distance, u = 1.1 cm
focal length of the ball, f = -R/2
= -1.5/2
= -0.75 cm
let v is the image distance
use, 1/u + 1/v = 1/f
1/v = 1/f - 1/u
1/v = 1/(-0.75) - 1/(1.1)
v = -0.446 cm <<<<<---------------Answer
magnification, m = -v/u
= -(-0.446)/1.1
= 0.405 <<<<<<<<<---------------Answer
The image is virtual
The image is upright
