Rankle #125 answer: frequency of electromagnetic waves (lowest to highest)

The answer

Rank by frequency of electromagnetic waves (lowest to highest)

1. 1AM Radio (broadcast band)1 MHz
2. 2FM Radio (broadcast band)100 MHz
3. 3Microwave (typical oven)2.45 GHz
4. 4X-ray (medical)30 PHz

Why this order

Ranked lowest to highest, AM Radio (broadcast band) (1 MHz) goes at the top and X-ray (medical) (30 PHz) at the bottom.

The closest call is FM Radio (broadcast band) (100 MHz) against Microwave (typical oven) (2.45 GHz), about 24 times apart. That is the swap most likely to cost a point.

The biggest gap is between Microwave (typical oven) and X-ray (medical), about 12,000,000 times apart, so that boundary should be the easiest part of the order to get right.

From top to bottom the figures span a factor of roughly 30,000,000,000.

These are the figures the game reveals after you submit. They are rounded; only the order is scored.

Difficulty: easier, judged by how close the tightest pair is.

How it was scored

right slot, one place out, two or more out. The score is how many items sit in the right slot, and only 4/4 is a win. Full rules on the how to play page.
